We shall see. But I can guarantee you, Gray's not dying. And if he is dead, it isn't permanent.

@Anon Erza has been much stronger than Gray from the jump, and Natsu and Gray were about equal for a while, and they still aren't too terribly far apart, but with Natsu's Lightning Flame Mode, he has an advantage over Gray that makes him stronger.
