I'm excited to see what the themeing will look like... the Imagineers are often very creative with what seems very limited. Still, I don't get the "cruise" idea for Living with the Land. Why would a cruise be passing through all of that food?
With the question of people leaving The Land after Sorin', it probably depends on what the food court is like. A lot of people might get snacks after or while waiting for their Fastpasses.
Here's the really interesting thing: correct me if I'm wrong, but isn't Sorin' the FIRST EVER major Fastpass attraction inside a pavillion with other attractions? (I'm not counting the extra diversions inside Mission: Space and Test Track as attractions, and Body Wars and Living with the Land don't attract "major" sized crowds.) Anyway, why is this important? Because it may cause people to get Fastpasses for Sorin', and then, especially because of the staircases, spend the meantime doing the other attractions in the pavillion. This would leave The Land ABSOLUTELY PACKED, which, by the way, will make the crowd flow in Future World even more strange, already having long, slow lines for Test Track, and crowds sitting outside of Mission: Space. Goodness this could be absurd. (By the way, this is NOT a criticism of Sorin' or anything else. I enjoyed the ride at DCA and an thrilled to see it in my favorite WDW park!)
