Mainly I guess...will it have ANYTHING to with Star Wars unlike 1.0? :lookaroun
It's a common mis-conception that the events in Star Tours take place during the first movie (Episode IV: A New Hope).
In fact, in the Star Wars timeline, Star Tours takes place *after* Return of the Jedi. It is its own story. (If you listen to C3PO's dialogue in the queue, he mentions events that happened during Jedi, including the Ewoks thinking that he was a god.) It also makes a bit more sense when you think back that the original Star Tours opened about 4 years after Jedi was released.
I don't have the specifics at hand, but in general, after the Empire is defeated in Jedi, there was peace in the galaxy. Leisure businesses sprung up, including Star Tours, to bring visitors to the various worlds. Among the popular tourist destinations is the "famed Echo Base of the Rebellion forces" that is advertised in the Hoth video segment in the queue. (Why would they give tours to a secret base while the Empire is still looking for it?)
C3PO and R2D2 find positions with Star Tours. But there is an underground movement, and the Empire is trying to reform. The battle that you encounter on the ride is yet *another* Death Star. Either they went back to the old design (not knowing about the weakness that led to the first one being destroyed), or the rebellion discovered a new, but similar, weakness.
Unfortunately, with the trench run being such a well-known part of A New Hope, and that the queue doesn't often back up to the point where Guests can stop and hear all the dialogue in the first queue room (and know Star Wars well enough to place the timeline), the fact that the ride *doesn't* take place during the first movie is missed.
EDIT:
Among the lines that place it in the Star Wars timeline:
C3PO: [In reference to the Hoth ad] Well you'd never get *me* to go back to that iceburg. [R2D2 beeps] I don't care *how* safe it is now, R2. It gives my motivators the chills just thinking about it.
C3PO: [In reference to the Endor ad] Things have certainly changed since we were last there. I thought we were doomed for sure. [R2D2 beeps] But we did survive...somehow.
C3PO: [After the second showing of the Endor ad] I really don't understand why they're not sending me on the Endor tour. After all, I am something of a legend with the Ewoks, what with my magic and all. [R2D2 beeps] Well the Ewoks *thought* it was mine.
