lelando: It depends which site you got it from. If it was some sort of auction site then obviously you won't get it on the launch day (either that or if you do it'll most probably be a Japanese Wii, if you're talking about the American launch that is).
What site did you get it from?
I went to EB a while back and preordered. Actually it may only have been a month ago, probably more... But I'm getting a Wii + Zelda:TP (and wii sports ofcourse) at launch, hopefully I'll have enough for Red Steel too by then.
Edit: What's WiiPlay?
