The Wii perfect storm continues. The OP was right in a sense that the huge Wii demand is not about SMG. But the OP is wrong because SMG is why the sellout happened when it did. SMG going on sale has ushered in the first serious promotional campaign since launch ast year. I am sure teh recent release of Metroid shorted a few stores but without SMG there would have been plenty of Wiis(At least for another week or so)
A year ago I never would have imagined 6-8 million Wiis not being enough for Christmas. Heck if they had dropped all of those for the Galaxy launch I don't know if it would have made it to December.
Final* Word on Game Delays:
The game will not be any better or include more content then planned. Any commnets that say so are just PR hogwash to make you feel better for having to wait.
Delays are due to lack of proper resources, skill, or adequate planning by the developer.
Do be thankful that they have enough respect for you to delay the game and maintain its intended level of quality.
