Will they flat out skip the movie? Doubtful. Will they care if they miss it? I'm going with no because that's what they've said (not being a mindreader quite yet I'm choosing to repeat what they've said not what they actually feel about the movie or what they'll actually do).
I'm hearing more buzz and hype for Avengers, Spider-Man, even the Hobbitt over DKR.
Again I will say, it's going to do well. It's going to do REALLY well. I just don't think it's going to do as well as Ray keeps saying. I'll be amazed if it does better than Avengers, and also if it's even a better film than Avengers.
