Read the novel. the ending of Ep III is exactly as Capt. Zissou says. Rick McCallum hinted as much about six months ago.
As for the ride, I thought the plan was always to put you in the pod race? I mean, the Geonosis battle was a ground battle. The Coruscant battle in Ep III has no real ending. As much as Ep I was reviled, a pod race would be a great place to accidentally end up with Rex.

I have some ideas for 5 new films in addition to a remastered version of the old one(Make the Death Star in the old Endor film the Death Star 2. Apparently in one novel, it acknowledges that Rex was there at the Battle of Endor. And replace that trench run with the run into the Death Star core)
As for other ride films I would choose 5 other planets:
The sign that once said Starspeeder 2000 is no longer in place outside of Star Tours. A couple months ago my friend and I submitted a complaint at City Hall requesting that the sign be fixed with the other 50th refurbishments and a week later the sign was gone.
Thank goodness. That sign was wrong for several years. I even took a picture of it and after seeing it a few times I asked a CM why the sign was wrong...she really didn't care.
