Given that he's now on everyone's radar, if they were to still save him for the third film, then the second villain could potentially feel the backlash of that since there's a chance that a lot of people would just be in the "okay, let's get this part out of the way so that we can see the next phase with Thanos".
Well, yeah, I think it's kind of obvious that Thanos is the villain of the next Avengers movie. I just think that he'll be popping up in the end credits of the next batch of flicks. Before the build up was about getting The Avengers together in the first place. Now the buildup will be about whatever Thanos is plotting. I have a feeling he's going to have a hand in all of the master plots from here until The Avengers 2.
What if the gems for the Infinity Gauntlet has to be collected through each movie? That'd be pretty awesome, I think.
