It seems unlikely that we will be playing as Hale again, but i suppose its possible. I'm sure alot of fans are wondering if he's really dead; I happen to think its going to be hard for him to come back from a .45 to the head. It was quite surprising that they actually did him in, I thought they'd find a way to save him, even though he appears doomed from the start. Will be interesting to see where they take it, but in my opinion I don't think we'll be playing as Hale again.
Another reason I doubt he'll come back is because if he does come back, wouldn't he still have his Super Powers, thus making the game rather redundant?
