What are you talking about, Thanos was NEVER said/confirmed to be the main villain of Avengers 2, he was just hinted at during the end of the first film. Yes, everyone got the jist that Thanos was going to be the villain in Avengers 2 but even Joss Whedon said at Comic-Con that he was surprised that everyone else was surprised about Ultron being the villain and not Thanos.
