Uhm...the same track layout doesn't necessarily mean the same ride. Take for example Indy and Dinosaur at Animal Kingdom: Exact same track layout. Exact same vehicles. TOTALLY different rides! I feel pretty confident that Disney won't make the same mistake twice in a row.
On another note, on the disney website, what's with the "personal farewell from Roz?" That's not going to be like the ET ride at Universal Studios is it?
