I don't know what Franky will get out of meeting Vegapunk, but I seriously doubt that he will just get something built into him without his input.
Oda is super sensitive about these things, as was shown when Franky found Vegapunk's abandoned lab during the timeskip. Yes he studied all the blueprints from someone else, but he didn't just make them his own - he took them and made them better. He even realised technology that the smartest guy on the planet couldn't realise. Why? Because Franky isn't just good with science stuff, he's also one of the best carpenters in the world.
So I'm absolutely expecting a high-five moment when we eventually meet Vegapunk. Maybe they will even create something together with Franky's unique skills. Maybe Franky even learned how to work with Seastone during the Wano arc, that could be something Vegapunk has no direct access to (at least not to this degree).
As for the Raid Suit, well I talked about that at length in the spoiler section, and I agree with both Miyamoto and Romance Dawn here. It breaks the pattern in the most disgusting manner - and thus won't be here to stay. The usual pattern being [privilege] + [hard work], just in this case without the hard work part.
! Great chapter. That's how an upgrade should be handled (Enma).
! It's a privilege to wield Enma, just like it's a privilege to summon Zeus, but it's still 100% on the user to unlock their own potential and the potential of the weapon.
! This chapter just illustrated so well what I was getting at in the past and why I don't see him keep that suit for long. Oda is not making an effort to let him grow into that gear, there are no hurdles to overcome apart from having the correct DNA, no indicated room for own growth due to the suit. You could slap the Raid Suit on pretty much anyone and you would get the same results. More speed, air walk, better defense, better offense, invisibility.
! And usually Oda IS making that effort, even when no one really asked for it:
! Luffy trains like crazy to upgrade his haki, the privilege is being trained by Hyou. Oda could have saved precious paneltime and simply noted how Luffy learned it by having the concept explained to him briefly. But no, several chapters are dedicated to hammer home just how much effort he's putting into that new haki attack. He's growing into it.
! Zoro's privilege is a new special sword, but it's extremely dangerous to use and has yet to be mastered. Another swordsman would be on the ground already. Oda could have let the sword simply be powerful and special and call it a day. But no, nothing ever comes for free for these hard-working protagonists.
! Nami stole the weapon of a Yonkou, but she's the only one who can make use of it due to her timeskip training. Oda could let her throw around Enel-level energy blasts without a care in the world, it's the weapon of Big Mom after all. But no, he's making a point that Zeus can only do that because he's fed Nami's special weather eggs, her signature move that she trained two years for. He's wasting precious panels for that because it's an important distinction.
! Franky's privilege was running into an abandoned Vegapunk lab, but he didn't just copy the work from someone else. Oda made it a point that Franky realized technology that was considered not posssible (at that time) by the smartest dude on the planet. It's on Franky, Vegapunk just jumpstarted his creativity. Who knows, maybe Franky's next privilege is working with Wano-craftsmen who can build delicate seastone gear. They craft seastone nails and handcuffs, Franky might create brass knuckles.
! Robin, Brook and Chopper have the privilege of Devil Fruit powers, but none of their abilities came effortlessly outside of the absolute basic functions of the fruit (resurrection, growing arms, turning into a human). Privilege + hard work. And honestly, in the case of Chopper and Brook I wouldn't even want to speak of a privilege, considering that those fruits are competing for the worst in the series (I think the Dachshund Zoan still beats them on awfulness, but it's close).
! Usopp, I don't know if he was ever privileged on anything, I guess one could say that he inherited the sniper skills of his dad. The hard work part is literally everything else, turning him more into a trickster enabled by sniping.
! Jinbe has the privilege of being born a fishman with special physical traits, the most valuable being underwater breathing. But as we could see with the Fishman Island citizens: 99,9% of all fishmen are hot garbage compared to anything living outside of East Blue. I think it's safe to say that his immense power comes from training and training alone.
! Now, Sanji's privilege is being born into a famous family of scientists, and his father created a power suit that only Sanji can wear. To this point there would be nothing unusual about it, the other Straw Hats also stumble into "upgrades" every now and then. But the second half, the hard work part, the "growing into it" part is missing! And Oda isn't even making an effort to add the hard work part, not even slightly! Why? Why is he not making that effort?
Sanji could have activated the raid suit, only to dash into a wall shortly after because he couldn't control the super speed yet. Maybe he could have missed the first kick against Page 1 because being invisible himself makes it harder to properly connect attacks (as he can't see his own limbs).
Nothing major, just something that hammers home that this is actually super difficult tech that needs a skilled pilot. Hell, one line could have been enough!
Instead he noted all the benefits of the suit and nuked Pageone.
"Super speed, cool. Super defense, cool cool. Invisibility, woopey! Let's ask Usopp to remove the swastika and call it day".
! You know, I don't want to convince anyone that the Raid Suit is lame, or that Sanji is cheating, or that he doesn't deserve it, or that he needed it because he was falling back on strength compared to Luffy and Zoro, or that he shouldn't wear it because of his Nazi family. These are different discussions that I don't want to get into, even if they are important (mainly the nazi family stuff).
It's just about the fact that this is an abnormal upgrade that doesn't compare to any other thus far. And I believe that to be the case because it's not supposed to be Sanji's upgrade. It's a red herring for what's yet to come. There will be an upgrade that will clearly catapult him back to the big boys, if he has ever left that zone, but it won't be the Raid Suit. Not the one he's wearing now and not Usopp's redesign.
! It's even possible that the much more digestable upgrades (Enma and Zeus) won't stay with Zoro and Nami. Enma could act like Zoro's Hyou, teaching him indirectly how to draw Ryou into blades. Maybe he will still be gifted Shusui because the locals are just that thankful, or the Nidai Kitetsu (what was the purpose of its introduction…?).
And Nami could have learned a thing or two by wielding Zeus, even if Big Mom takes him back at the end of the arc.
