I was thinking the same thing. I'm pretty sure this is just an update to Bigfoot, but in the future I'd love to see Mystery Lodge replaced with a flying theater. Every show of Mystery Lodge is nearly empty, they need something more exciting to draw crowds in, and away from other rides.
I also have severe withdrawals from Soarin' so maybe that's why I want it so bad. haha
I don't think they have the space, but one of Dynamic Attractions' new Dynamic Theaters would be awesome!
