I was wondering the same thing. Is he just super strong right now? Or can he do more?

he can move at super speed at the moment, thats it i think....i thought he might have got alot of his powers back at the end of last season when he touched sylar but aparently not =(

Peter needs to get to baby matt parkman, and see if that will get his full power back. We need someone to be just as powerful as Sylar once Sylar becomes whole again.

I think since he's Dad aborbed his powers, Peter can only use one power at a time. This new power replaces the old one like peter had Mohinder's super strength but then he touched Tracy and got her freezing power

we all be agree to give back Peter Petrelli ability. I tink the producer are forgot Peter`s girlfriend caught in the future, and Syler is stronger then everyone which is not fair. Are you agree with me. So producers thinks about this

It is sort of implied at the end of the season that peter is retaing more powers. at one point he has Nathan's ability to fly, then near the end of the season he took Matt's mind ability, then during the standoff with Samuel he flys into Samuel to tackle him then takes his ability to fight him off. so I think next season we'll see peter with his original ability again

Peter only has one ability at a time. It is inferred that (even though we didn't see it) peter touched sylar to gain the ability to fly and when he touched Samuel he gained his ability and lost all others. Otherwise he would have used them to defeat him. Remember thou, Hiro got only part of his powers back in the beginning when he lost them until he was cured by baby matt. Peter is still in the half healed state.

now Peter has a new ability after his dad stripped him off his ability, he use to be empaty (copieing every ability if he stands near the person), now he can only borrow ability's. Peter isn't in a half-healed state. He took the virus to get back his Abiliy but got another one and he is not happy about it. but i do agree that Baby Matt Parkman can help Peter like he helped Hiro
