Glad I preordered mine months ago, at a relatively out-of-the-way Blockbuster
Seriously, though, if they DO somehow manage to meet demand, or close to it, this game will have a bigger opening week than Halo. Guaranteed any extra Wiis they ship that month for the game will be sold, and if one store has 800 preorders (assuming they can somehow fill them), this will easily sell 5-6 million week one if they can meet demand.
