If this is actually official... spoilers, spoilers, spoilers, spoilers. And also yay for Hinata getting her Good End. :)
Yep. However these ARE technically spoilers, as some of the characters only show up at the very end of The Last, which transition to chapter 700 (specifically Uzumaki Bolt and Uzumaki Himawari).
why does Sasuke look like a hobo, like some random homeless guy.
Well, he kinda is(like Terry Bogard). He's wandering the world in search of himself(after banging Sakura). If any of Terry's romantic interest actually stayed alive for once, he probably wouldn't have settled down either.
