I for one am optimistic that there is something more than just Star Wars and Toy Story at MGM (don't care that it's DHS, I'm going to call it MGM to the day I die). It's one of those ones only time can tell whether or not we get something new. Besides there's so much open room there and with both new lands having no definite place where exactly they're going I think we could be seeing more coming (I'm pretty sure Toy Story Land is going behind what is
Pixar Place now but I just saw a fan image of it going over by LMA. While I doubt it considering how much of Mania's show building was in the concept art I'm not ruling it out)
