All this talk of the Avengers: Doomsday teaser has me thinking about the most shocking thing the movie could do. Marvel might play it safe in some aspects, but there's no way it doesn't swing for the fences before the movie is over. My bold prediction is that Thor dies, since he's already been around the block a few times.

I think some actors, RDJ especially, will play more than one role. I think there is zero chance he doens't also play some kind of Tony Stark variant in the movie (or maybe they'll save that for Secret Wars).
