I took a look at the strategy guide at my local EB Games.
Vehicle Confirmations: We already know about all the vehicles that will be in the game, either from the official site or from the x-box vehicle preview. Sorry, no surprises gusy.
Planet Confirmations: Bobby's Helmet has previously posted the complete 16 levels included in the game. Thats all of 'em. The big surprise to me is that Kyshyyyk (I know i am spelling this wrong) is mostly a tropical planet map. Lots of water & huts, quite contrary to the books.
Besides that, I didn't see anything all that important... just thought I'd confirm what we already knew.
