Agree, I think the pod race was just the segemnt of the ride that was finished enough to be shown at
D23. I think that you will see stuff from both old and new trilogy. I am hoping the rumor (not officially announced yet) that there will be random ride sequences making each ride different a reality.
If done right (and there is as yet no indication that it won't be done right) this could be as advanced a simulator as Star Tours was when IT opened originally. (At the time based on a 10+ year old movie BTW.)
There is no way they are just replacing the movie and keeping the identical ride vehicles. A (likely) year-long shut down means a pretty big overhaul.
However, is anyone surprised that they would announce something like this that won't actually be started for over a year? I guess I should be glad because it gives me at least one more chance to ride the old one...which I still get a kick out of, though it is not the thrill it once was.
