This is not the first big fundamental change to a character that marvel has done (Thor no longer worthy,One More day, the whole spider-man being a clone the while time and not ben reilly) and it wont be the last. And since i mentioned the clone saga I might as well point out the fact that some changes are not permenant. So yes the current writer says its the real steve. But there is nothibg to say a future writer wont use convuluted plot convinience, time travel, cosmic cube etc etc, to reverse this
