I barely attend Animal Kingdom and it's the only uncloned attraction so I voted Expedition Everest.
As for the rest, in decending order:
I want to see what occurs to The Land as a whole, not nessicarily just Soarin'.
I've seen It's a Small World's redone loading area, looks great, but it's more of a refresher. The year's wait makes up for the times I've just walked on.
Lights! Motors! Action! looks to be fun, but it's a clone from Walt Disney Studios Paris. WDSP. (I expect to see heavy Herbie tie-ins too... gag)
No high expectations for Stitch... I've seen the tricks they've used already for the show... now they'll be watered down. A decent storyline, as well as if the characters didn't talk down to us (tubey thingies), might change my opinions.
Cinderellabration, unfortunatly, doesn't look like it will interest me or the rest of the audience who isn't into the princesses. The thing about Cinderella's Surpise Celebration is this... it targets all audiences. Cinderellabration looks like a wedding ceremony (or a funeral, however you take it) and if the rumors are indeed true, the lack of popular characters AND the fab five might, in addition to the cut material from Toyko makes the hub construction useless. I hope this isn't true, but this is the impression I have right now of the show. Prove me wrong entertainment!
Lucky the Dinosaur isn't exactly breathtaking from the shots I've seen. It's just Push the Trashcan times ten. Animal Kingdom should've gotten a MUCH better clone for The Happiest Celebration on Earth, IMO. They need something to actually get me into the park.
