All the non-comic book lovers were scratching their heads at the end of 'The Avengers' when an image of the Mad Titan Thanos popped up in a bonus scene after the credits. Now, this big guy is the only thing anyone's talking about when on the subject of 'The Avengers 2.' We all assumed that moment was Joss Whedon's unofficial statement that Thanos would be our new villain in the sequel, but has it been made official? And what about the upcoming 'Guardians of the Galaxy' movie? Will Thanos be in that too?
