Dude.. the future has changed so many times. The old futures that we have seen have already been altered and changed. The futures that have been shown to us are no longer viable. If you recall, in the futures we've seen: The city was suppose to have blown up (that changed/didn't happen), The virus wipes out nearly all life on Earth (that changed/didn't happen), Super powers are given to anyone who wants/can afford them (that changed/didn't happen). So what makes you think that the future with Peter having his powers and being a badass is going to happen.
Oh yeah, and Claire is suppose to become a cold hearted bitch/killer. That isn't going to happen either because the circumstances have changed. Oh yeah, and how about Sylar being all good and having a son? Nope, that isn't going to happen either because you know what, he killed the woman who loved him and was going to have his child. So.. please, once again, you cannot possibly expect those previous 'futures' to hold any relevance to the current story.
I really don't even think that future with Ando killing Hiro is even going to happen, and to be honest I don't believe Ando killed Hiro at all considering we now know what his powers are and that they don't hurt anyone.
Also, Micah only had a small part at the beginning of Season 3 in order to explain that Tracy isn't Nikki to the viewers, and that Nikki really did die. We haven't seen muscle mimick girl since season 2 and I highly doubt we'll ever see her again. Kind of like that Irish woman that fell in love with Peter, oh yeah.. we don't talk about that I guess. After all, she was stuck in an alternate future that doesn't exist anymore.
