If I recall didn't MiceAge mention not too long ago that the Tron themed Peoplemover replacement was in consideration for a green light? While I love the idea of bringing an attraction back to the Peoplemover track I can't help but think that the lesson has not been learned that shoehorning theme after theme into one land totally degenerates the region as a whole.
A great way to fix this mess is to take one more fantasy-based attraction (Iron Man) that can provide a blanket theme for the whole region (50's-60's era Worlds Fair). At least this way even if there are a few out of theme attractions (Space Mtn, Star Tours, Tron, Buzz) you can overcome that chaos by building a blockbuster Iron Man attraction(s) for the guests to hypnotically gravitate to. Just like how RSR makes guests forget that Radiator Springs really doesn't have much to do with California.
