The problem is people, the couple of times I have been to the park it has not been crowded at all. So the big question would spending that kind of money bring more people to the park in the long run.
I guess the guy didn't bother to read the thread because we knew it was old and posted so on the first post. Might get a little traffic out of it anyway!
I don't think Disney really cares that they can't use Marvel in their parks in Orlando. I'm sure they are making a ton of money off everything else Marvel. They have plenty of things they can use to theme a ride or area and don't need the super-heroes.
