It's educated conjecture based on his dialogue and move name (Karma Retribution).
Ah, thought so. In that case. No comment 
Greg, now that we've seen Luffy's devil fruit awakening, do you think Oda will eventually do the same for Chopper, Robin, and Brook?
I think there's an argument to be made that we've seen the results of both being awakened.
If the Impel Down guards are truly awakened, their resemblance to Chopper's monster form is uncanny so it's possible that Chopper has been performing an awakened doping this entire time.
As for Robin, it's not necessarily an argument I buy but while I can confirm that Robin's giant forms are most definitely composed of smaller body parts, I'm not entirely sure about the smaller copies of herself that she can make. The argument is certainly there for suggesting she creates the illusion of clothing on a smaller scale via varies body parts and pigments, but then the question becomes, why doesn't she for larger forms? Or if she can't do it for larger forms because it's too taxing, then why bother doing it for smaller forms? In that case do clothes magically appear on her because of the magic of clothing and Devil Fruits? Well…then why don't they appear on her larger form?
While all valid questions, they're not really important and I can almost guarantee that there aren't clothes on giant Robin because...Oda doesn't wanna draw 'em. That's what it boils down to.
So, if that's actual clothing on small copy Robin, and it's not just DF magic, then it could mean she's duplicating her clothing which would very much be an Awakening trait.
I think it's all a matter of convenience/preference on Oda's part so I don't feel particularly strong about it one way or the other.
So with that frame of reference, if Robin is not Awakened, I feel very much that a conflict with San Juan Wolf would be the perfect spot for it so yes, I do think he will explore (or expand) it.
Greg, what do you think about the increased focus on Raizo?
Not much, it's par for course for any given arc. Raizo is fulfilling the role of containing an element of 'chaos'. There are always characters who take on these roles. Who it is isn't always necessarily important so long as someone does it.
In this case, I do think Oda had planned out Raizo's use from fairly early on in the stream of events. I think when the fire started he knew it would be a large element of chaos and it needed to be dealt with and he knew that Raizo would be perfect to deal with it so he just needed to keep him in the game until then.
Sometimes, in arcs where chaos resolution hasn't been solved in advance, Oda can pick and chose basically anyone from his grab bag of goodies to fulfill the objective so long as it feels right in the moment. This is why we got Gatz carrying Luffy through the town. Luffy was separated and weak. Oda needed to get him safely from Point A to Point B, at the time, Gatz felt best and most appropriate for the story to fulfill that role and express self-sacrifice so I bet that's why Oda chose him.
Here, it's the same exact thing, except I'm almost certain Oda planned to have Raizo be the resolution in advance.
So, business as usual in One Piece.
If I may ask, Greg, do you have an vague idea how much of the Wano arc is left based on what Oda and his editors are potentially up to?
As far as inside info I don't have any info on how long Wano has left and I definitely don't want it ^O^ Aside from a few other things like the role Elbaf will/won't play and whether or not Pudding/Streussen are as important as I think they are, it's one of the few mysteries left for me.
I think as soon as the Momonosuke starts to show true spine, we'll see the fighting start to wrap. But then we'll have the chaos of a falling island.
UNLESS…Oda wraps both of those up simultaneously. If he does that, I'll be amazed. And I don't mean that I don't think he can. I literally mean, that would be a very difficult way to wrap the story in a satisfying way.
