I don't know why almost everyone think WiiFit is going to sell that much. It's not an established franchise, it's expensive and it probably won't be that much of a fun (it's not a game afterall). I'm not saying that WiiFit won't be a hit and won't sell a lot eventually. But I find it very unprobably that it will start with mega number like 500k. I belive that it may actually become a phenomen but thanks to its legs not massive first week sales.
SMG is an established franchise and sold only 250k so what do you expect from new title with higher price which isn't even a game? WiiFit won't sell becouse you want it to. This is the same wishful thinking you've used with SMG.
My first prediction was 50k first week and I actually thought that it was a little low. But after second thought my opinion is that 50k may be even a bit optimistic (and not as bad start for the title).
PS. Anybody knows how many WiiFit will be avalible first week?
