While I was scouring the internet for some Rock Band fix (since it's crack cocaine in my blood stream) I ended up at RockBandGame.com (which up til now i had no idea existed actually, since rockband.com has developers blogs and what not), but either way I'm looking through this flashy rockbandgame.com and notice the preorder button, so naturally I click it and it gives you the options of GameStop and BestBuy, so I check both:
BestBuy has both (games only)listed for a 11/13/07 release on PS3 and 360. No peripherals listed however. Listed at 59.99 as usual.
GameStop on the other hand, has the games, peripherals, and bundles all listed (with prices) for a 11/20/07 release. Game same price, the wireless guitar is $20 more for 360 as already posted, and the bundle of all the insturments is the same 199.99 for PS3 and 360 alike. It does include the wireless guitar, a drum set, mic, and the game itself. Not bad, since if you each part alone it'll set you back $249.96 - so you save $50.
Which date is the real release date? I'm leaning towards the 20th on this one, since GameStop seems to have a lot more info on the game, peripherals, and offer if you preorder by the 19th you're gauranteed to get it (if you overnight) on the 20th. So they're offering a lot more than BestBuy too, who just have the game. So it's not set in stone, but look for Nov. 20th (give or take a week at most).
