Also, why the heck would Claire still be alive in the future if Sylar supposedly has her powers, he only acquires them in the future we just saw.
So in conclusion, if future Sylar didn't get Claire's powers in the past... that could only mean that Peter saved her and should've gained her powers in this current timeline.
The only other possibility has to be that in this current Future, and in all futures Sylar never actually acquires Claire's powers in the past... with or without Peter's help, that it was simply a misconsception by Hiro and he survived Hiro's stab some other way unknown to us.
