@foolkiller1: I think that it is just a picture of past and present Avengers since it is a 50th anniversary issue and not necessarily representative of the current characters. I think that is Richard Rider as Nova and he has been MIA since Thanos Imperative and Moondragon died in Annihilation: Conquest. I also thought the guy with the Britain mask and long hair was alsodead but i'm not sure about him.

@Cap10nate: Ah, ok. Forgot it was the anniversary.

That's not even funny.

Heh wonder if they allude to what'll happen to Bob?

You got me so excited, and now I am sad.

venom looks like he's trying to assassinate spidey

@foolkiller1: There are several dead characters on those covers, not just sentry. Must be the anniversary thing.

yeah, I shouldn't have posted this, I just saw the sentry and reacted.

I has a dream last night where everyone was raving about the Sentry being a bad-ass. Kinda want him back now.

Boy do I not want him to return. Only way I would be ok with him coming back is if he took Blue Marvel, Hyperion, Count Nefaria, Ethan Edwards and other Superman wannabes into nothingness. 
What I liked about Marvel was there lack or Superman. 

I would actually be ok with that if it happened.
