I like Star Tours, but at the same time, i'm not sure how much i'll miss it. Also, I really was down on the ride when Jakku was a default first mission for about a year. Now i'm sure it'll be the same thing with this new destination, too.
Basically, the ride makes no sense within the realm of Star Wars canon since they switched to ST2.0, so losing it, when we have an entire land based on the franchise, for maybe a lesser IP to get a ride isn't something i'll really be too upset about.
People keep saying Indiana Jones, but that's the lazy way out for Indy imo. There are two better rides out there with the Indy IP than what the ST/Body Wars system is.
Anyway, I think that The Incredibles or even something like Wall-E could be good guesses, but who knows, maybe they just decide to bulldoze the building and the restaurant next to it and start from scratch?
