The future IS set in stone

SPOILERS!!!:
So as we've all come to notice, the future episodes seem to be heading toward the path of "not so much going to happen". Time and time again we come back to the concept that either the future is or isnt going to happen. I read something that finnally tipped me over the wall.
I was just randomly searching around for season 4 plot and such..."spoilers", and I found something concerning Greg Grunberg's character, Matt. He says that when he mezmorized Sylar, he sort of stole his soul. SO a peice of Sylar is living in Matt, but Nathan is living as Sylar. The Sylar in Matt eventually decides to try to corrupt Matt, but Matt is unwilling. Eventually, Syalr kidnaps Matt's son.
You all are probably thinking, "How does this have anything to do with the future"? Well, when we all saw the season 3 future episode with daddy Sylar, and baby Noah, then we saw Elle die, we kind of figured that that future will no longer be happeneing. Well who's to say that baby Noah is even Sylars child. Maybe baby Noah is actually baby Matt, that Sylar steals.
And just to prove it to you, in the season 1 future episode, "Five years gone", We see Nathan being president. But at the end of the episode, we find out that Nathan was actually Syalr in disguise. Well it's finnally happened. Sylar killed Nathan and took his body, just like they said he would. So the future that they show us will really come true.
The only problems I see with this theory is that I don't think they could bring back the Shanti virus, better yet they shouldn't. But season 2 was a fluke. And also in the season 1 future episode, I think Peter was dating Niki. But Niki is dead. Unless they didn't actually say Niki, then it could be Tracy, or Barbara. And in the season 3 future episode, tracy was dating Nathan. Or maybe that was Barbara. But Nathan wasn't Sylar at the time, because Sylar was somewhere else.
So never mind... If Nathan is alive in the season 3 future ep, then maybe the future doesnt come true....
But then again, maybe the season 1 future will come true, and not the season 3 or 2... I'm confusing myself. this was a waste of a thread. Please reply.
