I think it's interesting how everyone in this discussion seems to be under the assumption that Sunset Blvd. will stay if ToT becomes Guardians. what's really there in Sunset Blvd?
The dated Beauty and the Beast show? That's in desperate need of some upsdates and new costumes. I love that show, but when I was there over the summer, the lack of passion in the performers was evident. Something has to be done with that show.
Rocking Rollercoaster? thats already supposed to be getting a retheme with Big hero 6 as a rumor ivr heard thrown around.
The entrance to Fantamic? Move some stuff around and maybe enter through the exit near the front of the park.
That's it. I absolutely hate the idea of ToT being rethemed, but I think we should stop thinking of how it would ruin Sunset Blvd and start picturing Sunset Blvd becoming Marvel Avenue. Replace Beauty and the Beast with a stunt show or use thay space for smaller scale attraction (a dark side or flat ride probably). Retheme the buildings and shops.
If they go with the Tower retheme, I'm almost positive it will be at least partially because Disney wants to make a Marvel land as the next big step. One ride in epcot is one thing, but there's just sooo many reasons why they could never build a whole land there. That would explain turning their attention to the tower.
