Peter losing his abilities might turn out to be a good thing actually.
Its possible that Peter will once again become the most powerful hero with the loss of his ability before the others, after the eclipse. As he would be the most adapted to dealing with situations without abilities. So he will rise amongst the heroes and lead them to deflate the villains before the eventual showdown in episode 13 'The War'.
Of course by then, they will all probably have their abilities back, very likely as a result of mohinder's research of the formula and claire as the catalyst. But who knows what peter would have done to deflate, demoralise the villains while they are all abilities-less.
They always need to keep somekind of check on Peter and Hiro, a reason they won't use their power to full extend, else they are just too powerfull. Peter is overly dramatic and Hiro naive and lately he doesn't want to time travel anymore.
The same counts for Matt and Sylar to a degree. If Matt could watch from a distance and get a good view of what's happening he could be a powerfull player, nearly no one could stop, but they send him to africa, keep a "spy" near him something like that. Sylar is constant struggling with his power, with his friends/family, his past, his personality.
It's the same reason that you know Arthur is going to die or become powerless. He's too powerfull to keep around. Everyone who seriously becomes a problem can be killed by him without much more than a thought. It's teleport, steal powers, disintergrate.
