Can't wait.
Physically and maturation-wise, I hope that they don't change all that much. Much of the humour stems from their maturity level (as well as the series' light-heartedness), while I simply like the character designs and am hesitant of a design change.
I think that neither character will drastically change their fighting style; meaning that there will be no new physical weapons. Obviously, there will be the obvious inclusion of 'haki' - perhaps by even Zoro, too!
As for the marines, other than the Buggy as Shichibukai and Ao Kijiji as Fleet Admiral, I'm fining it difficult seeing anyone else pick up those replacements. Though Coby will obviously play a larger role, it just seems as if it's far too sizable a gap for him to fill. Admittedly, I may be underappreciating how long this time skip is relative to how much time had already progressed.
I haven't actually formally written or even thought much about what is going to happen. I'll be sure to do that and revisit the thread later.
