We'll find out once Naruto kicks Sasuke's ass =D Or whatever the result of the fight is.
As for wanting Chouji dead, I'm not saying he's a crappy character or anything...even though he has been fairly worthless until recently. I doubt he's dead, but I think it would have been a good death for him. Proving his worth and dying an honorable death. Not to mention self-sacrifice. It's just a very noble way to die, and it's suitable for Chouji's character. A death like that would be well deserved.

But I'm still sticking to my "no main (good) character dies in a happy anime" theory. So to me, he ain't dead. =)
