Spoiler:

Well one of mine is that the grandpa that Aokiji is talking about is probably mean. He probably was the one that let Ace and Luffy stay at there house. Maybe he made them fight each other?? They did fight when they were young. If this was the case, he probably favored Ace which made Luffy mad.

Another one of mine is Gol D. Roger's crew still being alive somewhere. Maybe the Pirate King himself is still alive .

Spoiler:

Hmmm..... I also think that the next arc theyre going to get there carpenter. And I for some reason see more of Luffys past being revealed.
