Xbox 360: Zero Hour Event
Microsoft has just opened up the Zero Hour contest, where you and a friend go to some place in the Mojave Desert and play Xbox 360 games a few days before the system is officially released. Do you win the system? No, but you do have the awesome chance to buy the system right there and then. No worries about shortages! (LOL)
Anyway, sign-up is on this page

but you have until the end of the day to do so. And Microsoft will only supply you the tickets if you win; you're on your own in terms of getting there and lodging.
