I lurk through this thread often, but after seeing this rumor I had to post. I've rode the Superman ride at Great Adventure and was not crazy about the ride and the position you're in. Have yet to ride the Manta coaster at SeaWorld. BUT....I've been saying for years that Marvel needs a new ride/expansion, especially where that amphitheater is. Also, Iron Man is my favorite hero and always wished he had a bigger presence in the park. Especially now with the movies, he's in the upper tier of Marvel heroes with Hulk, Spider-Man etc. So I would totally welcome this potential ride.
And I agree about the cartoony feel of MSHI. It just feels so 90's. And as a 90's kid who grew up with those Spider-Man, X-Men, Iron Man cartoons , it's like a step back into childhood. Love the whole environment. My personal favorite land in Universal
