That video really does give a lot of hints at what they are trying to "sell" to the public. Looks like there will be weird "alien" type food, and merchandise. The "night time nature walks" is another hint that Disney will be pushing Avatar at night to the public. It also emphasizes "family" , so I'm thinking the "canoe" ride will be rather tame, with not any giant drops or Rapids.
Interesting. It totally feels like a homage to Epcot to me in some way.
