Tuesday? Been waiting for this game for a long time. But... why release on a Tuesday?
If you release the game on a Monday, then if anything comes up last minute when folks come in Monday morning, you're SOL and might have to delay launch.
If you release the game on a Friday, then if something seriously breaks, you need to hope all your support people/programmers are available to handle the fallout.
If you release the game on a Tuesday, you have time to prepare for the launch, as well as time to fix any last minute issues while there's still a work week left.
