The SMH has an article about it and how in the US the Wii sold at a rate of about 1 per second in it's first 8 days (600,000 units), and sold about 3 times as much as the PS3.
I'm pretty sure it'll sell more than 3 times the PS3 here at launch, but that probably because Sony couldn't be bothered trying to get any units to Australia until sometime in March. Thanks Sony - nice job! (not).
P.S. There's more Wii videos on the UK Wii site if you're interested.
