It took me a week, but I finally got through this entire thread.
I'm not convinced that Star Wars is taking over the space as indicated by
@Ignohippo -- not because I think his info is wrong, but because I'm skeptical that it has been finalized. It sounds like plans are still fluid and we are probably 2 years from building being started, so who knows what will happen. If we get some independent confirmation, then I might think differently.
As for the planet used debate, I'm somewhat agnostic. I think the "right" way to go would to have done an established place (most likely Tatooine). I disagree with others that it would have been out of place (who cares if it rains) or not interesting enough (we've seen plenty of shots of Tatooine that could be developed into a visually interesting land). That said, I'm okay with the new planet if it allows for more creative execution and a better theme park experience -- especially since it is almost certain that the planet will be featured significantly in the upcoming movies. By the time the theme park land opens in 2020-21, the planet will probably seem familiar.
As for the rides, the general vibe I get is: Star Tours is likely to stay (and may or may not be included in the 14 acres), the Falcon ride will likely be a simulator of some sort but I expect it to be smaller compartments with a lot more movement (having it be a Kuka ride does make some sense), and the other ride is probably the LPS one hinted by Miceage -- while surely screens would be used, I expect large footprint for that building a significant physical sets.
