Not a HUGE deal, but for the folks who follow the comics ... Marvel films and comics seem dead set on making Tony an a** hat. Civil War, the current 2-year 'Time Runs Out' Illuminati Story ... I really think after seeing the AoU trailer, the cinematic universe is also going to make Tony the bad guy. Not the major villain, but again, if you read the comics, Tony can't seem to get a break. I think the reason we won't be seeing an Iron Man 4 is due to the antagonist role he will play post AoU.
