Well, nothing lasts forever. Comics from DC and Marvel have proven that time and time again. But, it might take a while for it to get changed back. Usually happens when creative teams start to get switched around.
Look at Kraven, he's been dead for how long before they decided to bring him back from the dead. I'm still waiting for Ben Reilly and Gwen to be still alive and Uncle Ben goes around town in his RV with them in hiding to stop evil aliens.... *waits for people to get the reference*
