About Hancock, I don't think she was there purely for the comedy, but I also don't want Luffy to end up with her only for pity or because she'll die, he'd better stay alone then if it's just to not break her heart. What about Luffy's happiness? He has already stated he wouldn't marry her… I love Hancock and I don't want her to die but if she is to end up with Luffy, they need some serious development, and soon - we're set to the EoS now, these things take time to develop. To Hancock, either she'll actually die for Luffy, or she'll find someone else who reciprocates her feelings.

Luffy and Nami is more likely, they have a lot of things going for them. I'd rather not see them getting too romantic with each other though, what I can see happening is more of an implied relationship than an actual marriage.
Zoro x Tashigi need more development, but they're on the right way and Oda has even implied that Tashigi might feel something for Zoro. He also gets so easily pissed when she's around, even after overcoming his issue with her looks.
Usopp x Kaya = canon.
Franky and Robin are not canon (yet), but they already act like a couple, seriously. They have a history together, they interact a lot, Franky called her "beautiful" and "super", he complimented her ugly drawing, they talk a lot to each other even in the background. Plus he slept on her lap and they wear matching clothes, classic couple stuff in Japan.
Chopper x Milky, which in SBS #82 Oda heavily implied she was Chopper's endgame.
I can't see Brook romantically involved with anyone (maybe Cindry-chan, but that won't happen).

Right now, the only one hanging on the line for me is Sanji. Viola, Pudding or someone else? Nami, I don't see it happening but I won't rule out that possibility. Personally, I'm waiting to see his development with Pudding, and her real intentions, because I'm feeling tempted on supporting them. I don't think they'll marry now, but I can see them meeting again after he fulfills his dream.

I agree with this post, And your parings!

I think since dressarosa arc Oda has broken his previous statements intentionally because he does intend to develop light parings for the end. Sanji and Violet was obvious romance, sai x baby 5 etc. To me Luffy-Nami is something that will occur towards the end after a timeskip or so when Luffy is no longer a kid. The amount of development between him and Nami, rescue arcs, movies, resemblance to roger-rogue, epic moments is just too many to seem as coincidence. Plus Nami in my opinion since Zou has been showing more feelings for him and I think will grow from there.

Hi :]. Ya Oda never said 'no romance' he said 'they are in love with adventure' and there has been tons of Romance last few arcs from Dressrosa. Shocking one to me besides Sanji and Violet was Baby 5 and Sai? I loved baby 5 and I thought she would join the strawhats, they needed a gunner and someone hillarious to match sanji xD. But to me Luffy-Nami has the most evidence to develop as we near the end along with Usopp-Kaya and Zoro Tashigi. Luffy-Nami had this intense opening episode and the most serious moments together.Btw this Youtube guy does One Piece reviews he doesn't care for romance but he made a interesting video on 'romance in one piece' and uses evidences

Though I love one piece for the comedy/story, this stuff has been bothering me lately. Man to me Hancock was just comedy, she is hot and interesting but her role was to get Luffy into Impel down in my opinion. To me since episode 1 the nami-luffy interactions, story lines, rescue arcs, even movie focus(like strong world) as well as in critical moments its normally Nami always seeking luffy. I think Oda wants no romance to steal focus from the story, but I think he has promoted this pairing in most arcs though subtly. Also without a navigator and namis brains Luffy cant be 'free' and adventure if you think about it she is his most important ally. So I like it to happen. I get your point on the main guy x main girl, but honestly beyond the hints of NamxLuffy moments arlong park, skypia, Strong world etc and Zorox Tashigi(or robin), I don't see any hints of other possibilities. But It will be very interesting when Hancock meets Luffy and Nami. Also when Ace died Nami cried for luffy, and I have a feeling dragon or shanks will die also soon at the hands of blackbeard, interesting to think about.

(Spoilers from manga!!!) Man I was disappointed baby 5 did not join the strawhats she was awesome and hilarious she was perfect for the crew, but now I kind of want purin to join thew crew. Its possible Sanji marries her to save his 'nakama' from big mama (and cuz purins is his type), Purin joins, big mama may ally and lend luffy some help vs Kaido! I personally think by the end of the show Nami will have overt feelings for luffy both of them are the main guy-girl characters of the show, both of them have the most Hero-damsel scenes and hopefully by the end of the show luffy will be more grown like Shanks. I think by the end not in a romance way but more comedic way( without luffy realizing it) Nami will show over feelings for the goofy luffy ( he is future pirate king after all). Nami knows luffy is her man since the Arlong saga. And yea this is a comedy/adventure but it is interesting the last few arcs Oda has put in more comedic/romance type stuff with the Baby 5 x Monkey guy, Violet and sanji, now the marriage thing. I think we will only see bits of this more by the end. And next arc maybe we will see Zoro and tashigi meet at wano as well!
