I probably will. Usually get stuff at about 2 AM my time on XBL when I stay, so I should be okay.Who else is going to stay up all night on tuesday so they can play the game right away?
Of course, this doesn't apply to people who already have the gosh darned game.
Also, watching some reviews and walkthroughs on YouTube and I'm amazed at some of these environments. Seems like the game just gets more and more interesting visually the further in you get.
