For the most part, we have the same info. I stick by what I've said about that building, but it could certainly be incorrect.
I'll just say this. The new attraction is going where Indy is now. The Queue line (at least according to the VERY similar plans at DL) snakes directly in front of it, just behind what is now Echo Lake. The X-wings, etc. will be going around the area of where the Indy store is now.
On the DL plans, the area where 50's Prime and Hollywood & Vine are is trees. IF the new attraction plans are basically the same (and given that Echo Lake is almost EXACTLY where they have the body of water in the DL plans), then what do you think would happen to that building? It certainly wouldn't remain with the architecture they have now.
Given all the other info I was given has been spot on (and there's certainly the possibility it could be completely wrong and SWland could be going in Streets Of America area instead, which it isn't) and that everything has been pretty much confirmed by the leaked DL plans, I'm sticking by what I was told. Now that they're also touting this new restaurant experience (which no one ever mentioned except for me), I think it remains more than likely that these are the current restaurants re-themed.
