I don’t think that Ant-Man and Wasp will get their own features, and I’m not sure they will even get into the movie. I think that Captain America movie is in the works right now so he will probably be next.

Also, I believe the Wolverine movie is a prequel to X-men talking about his origins based on the Weapon-X story. But it’s not out of the question that they might try to smuggle him into Avengers since he was a member of The New Avengers at some point.

Another established superhero who might be in the Avengers movie is Spider-Man who I believe joined the team somewhere in the 90’s (at least according to Wikipedia). I guess we will see how it goes.

I’m very curious as to what will be the the Avengers team roster in the movie.

A couple points you said that I want to touch on:
Banner in this movie has been the Hulk for 5 years. As shown in the beginning of the movie, he’s been doing what he can to control himself and keep himself in check. This is more about him coming to terms with his predicament, rather than suffering from it. He doesn’t change when he’s angry in this movie, because he’s working on controlling that.

I’ll agree, they probably could have cast a better Betty Ross than Liv Taylor. However, I don’t think she’s as bad as you made her out. The relationship between these 2 has been around for years. It doesn’t develop because of that, the relationship has been there. The problem from that comes from that fact that not everyone is familiar with the story. People who’d have read the comic or seen the series would know and be fine with that. Those who’d haven’t watched it before, would be wanting to know what their relationship was. This is a bad example to explain what I mean, but picture never having read/watched Spiderman before the third movie. Would you be asking why Parker and MJ are they way they are at this point in the series? I think the part she played best in that movie was Ross after the taxi ride.

As Hurt’s character goes. Thunderbolt Ross earned that nickname because he’s over the top with the barking orders. I think Hurt almost nailed his character perfectly. His conflict isn’t him deciding between duty and family. That decision was made. He acts on duty first and uses his daughter as his reasoning for doing what he does. He is purely obsessed with capturing the Hulk and proving to his daughter what a monster Banner is. Thus the scene on the campus where he makes the comment “Now I’ll show you what a monster he is.” Their relationship can best be summed up by the line “the only reason you’re not in cuffs with him is because your my daughter”. In general, capturing the Hulk is an obsession that he’s doing for duty, and claiming his doing it because the Hulk is hurting his daughter emotionally. In reality, he’s too blind to see that he’s the one hurting her. My only complaint about Hurt’s performance is he needed more of a temper.

Anyway, those are my initial comments. I’m interested in seeing how Stern’s character is going to develop as the Leader in the next movie. Of course, I can’t wait to see how the Avengers movie is going to be. Who do you think they’re going to make a film about next. From what I’m seeing, the next Marvel Movie is Punisher 2, but the next movie with an Avengers member is the Wolverine movie in May 2009.
