I think that Thanos is better suited for Avengers 3 than 2, he would be a great trilogy ender, and would make more sence considering that Whedon said that Avengers 2 wouldn'tbe bigger in terms of scale but in characters, so i expect Avengers 2 to have Ultron and Avengers 3 to have Thanos, something similar to the Liberators could be possible too considering that the united nations appeared and didn't really like Nick Fury's decision.
