Which Of These Heroes Is Dead For Good?

We saw two of our "original" Heroes protags die in last night's finale. Niki was trapped in a burning building when it exploded, and Nathan got gunned down. But sources say at least one of those deaths may not be final. Did Peter fly Nathan away to get medical help? Or did Niki climb out of the burning wreck in time?
