Hmm...well, there was something that I put in that I haven't seen anyone mention, but then again, it COULD have been deleted at the last second by the Level Designers...
On Coruscant, when you're talking to the horned guy (who give you the tour tickets), we originally had a Millennium Falcon model flying around behind him. As I recall, we were waiting for LEC to notice it and tell us to take it out, but that never happened as far as I know. Has anyone seen it? It's pretty clear in the background while you're in conversation with the guy.
I'll say again, it could have been taken out. I know it didn't make the PSX version, because the ship flew into where one of the buildings was on that level version, so it got axed. If you don't see it, don't be too surprised.
