So. Usopp is now fat. I. . .don't really know what to make of that.
As for the story, more setup, but this brings some interesting ideas to the table. Whitebeard shows up with a fleet of pirates from the New World, and he completely bypasses the blockade. Also, looks like someone opened up the gates for Luffy and his crew of renegades, but who? Hancock would be a likely candidate, but she's been with the Shichibukai the entire time. I'm guessing either Blackbeard (From Impel Down) or Dragon.
I think it's very interesting that Whitebeard was setting Ace up to be the new Pirate King. It seems Oda is setting up Ace to be one of Luffy's final opponents, along with Blackbeard.
Looks like the next issue is going to bring the thunder. . .
