The Wii arrives this coming weekend.

I have a Wii reserved at a local Gamestop, but they tell me they are only going to get enough copies of Twilight Princess in for preorders... the problem being that I refused to preorder Zelda.  As a result, I'm probably going to head to Wal-Mart at 10 pm and pick up both a Wii and Zelda there, where there will not be "only enough copies to satisfy preorders."

Does anyone else find it ridiculous that stores won't have at least enough copies of a launch title to be able to sell one for every system they have?  Or that I'm going to have to go to Wal-Mart to buy both my Wii and Zelda, as picking up my preorder would result in not having a game to play?
