Yeah Ultear is most likely dead, Hades already told her she can reversed the time of all things but her own time since her time is the thing used to activate Last Ages. And don't talk about these things:

"How much magic power is used for one minute? Then, how many years would that come to in whatever vast equation you calculate with for how much time she is capable of giving up? Since the factors don't have numerical or other recognizable value, I can't think of an appropriate equation to put it into."

Cause it means shit in Fairy Tail.
