Wii Shipping Dates?

Does anyone here have any concrete info on the shipping dates of the Wii?

Obviously, the first wave will basically sell out within minutes (maybe hours) of it's initial release, so I don't hold out much hope for getting one right away.

However, I'm wondering when the second wave, or possibly the third wave will ship to stores.

Does anyone know?

I know that Nintendo is supposedly shipping over 4 million units on the first wave (compared to the 400,000 units that Sony is shipping), so my chances of getting one are probably a lot better than getting a PS3 (which doesn't interest me in the least).
