Thanos will likely make an appearance in Avengers 2. He's going to be showing up in Guardians of the Galaxy, although he's not the main villian there either.
They're building it up to show that he's been pulling the strings behind the scenes and in Avengers 3 he'll be the true villian.
Avengers: Age of Ultron will be released on May 1, 2015, and it will be directed/written by Joss Whedon, who directed the first film.

Why is avengers 2 called age of ultron? Who is ultron?
Ultron was a robot built by Hank Pym (Ant Man, Giant Man, etc). its body is pure adamantium, the indestructible metal that Wolverine's claws are made of.
Ultron was programmed to enforce peace ... and of course it soon decided that the best way to achieve "peace" was by killing everyone. no humans = no war ...
due to its indestructible nature, Ultron was one of the Avenger's biggest foes. and because it was an Artificial Intelligence, it learned how to duplicate itself, and kept coming back. and back. and back ...
we're not sure, yet, how much of this will carry over into the Avengers film, since Ultron's inventor hasn't been introduced in the movie-verse.
Who do you think is going to make ultron in avengers age of ultron?
I think building an uber-powerful, homicidal robot is far above Hammer's brainpower. Ultron (don't know anything about his abilities or powers, just speculating here), if he is powerful enough to challenge the *entire* Avengers squad AND S.H.I.E.L.D, I think someone more...ingenious would be behind his origins.
I mean, poor Hammer couldn't even replicate the Iron Man suit/technology without crippling some poor test pilot.
I could see the Council (those floating heads on the screens, sitting in the dark?) being the mastermind behind Ultron. That the world is scared of the strength of Thor and the Asgardians, and instead of relying on S.H.I.E.L.D. and the Avengers to protect them, the Council builds Ultron and loses control.
I heard James Spader's been cast as Ultron. If so, it'll be an Ultron skinjob for most of the movie, and in the climax there'll be a scene where it's all peeled away. Basically like the original Terminator movie.
The world has not yet seen a Batman/Superman team up on the big screen. If it is handled properly, it will be bigger than the avengers. While comic fans know who Ultron is and how tough he is, most ordinary movie fans will say, "Ho-hum, another robot" and will not care about how cool the avengers are. That's my take on how the general public will react.
I agree-either Hawkeye or Black Widow. Neither have superpowers or a powered exoskeleton (though they seemed to manage well strangely in the battle of New York), so they would probably fall first.
On the subject of the Avengers 3, I'm not sure that will even happen. I doubt all of these actors (Downey Jr., Evans, Hemsworth, or Jackson) really want to be tied down for yet another Avengers film. First, they'll start to be typecast for the same roles they played for 6 years or so. Second, in my opinion, Marvel is oversaturating their superheroes. Film after film after sequel; short films; even a generally unpopular television program.
But yes, I think some of the human-based, non-superpowered characters will die.
Ant Man will no be in The avengers I'm sorry to say because they are changing wat was in the comics to the movie. Ant Man made Ultron in the comics but Iron Man will be making Ultron in the movie.

Ultron uses A.I.. I think he'll take over Tony's suit and fight Hulk with it. This will be nice character development for Tony, seeing as how they could play it out like Batman. Where he creates and saves stuff that he can take down each member of his team with, making them not trust him. Also, if you watched the Avengers 2 teaser trailer from comic-con, it's apparent they're keeping his comic-book head sculpt. And Ultron's copies can be seen in the Quicksilver concept art. So if you put those 2 together, that's what Ultron will look like. I'm freaking pumped!
