Outside of Imagination (which is still vague as to what it's really going to be), this is still the thing I'm most excited for that is coming to WDW in the next series of years. It seems like they're really making it fit the park and are not going to sacrifice it being a big, scary adventure to do that. And while we've lost a cast of dinosaurs, at least we're apparently getting (at least) one very large, imposing new AA creature with this ride.
I'm psyched for the whole Tropical Americas area, really. New Indiana Jones ride (with Disney aiming for it to be the best they've done so far) and a classic, AA-filled dark ride? Plus, hopefully, some interesting food and AK's usual attention to detail in land design? Sounds pretty ideal!
