Luffy unfortunately won't be meeting Shanks or Whitebeard, so it'll have to be one of the two unknowns, possibly both.
I wonder if Ace is still chasing after Blackbeard or perhaps if he's returned to command the 2nd fleet.
Also, Coby looks recognizable but what the fuck happened to Helemeppo? and, Coby's headband thing for some reason reminds me of naruto...
