I'm an avid, happy 360 owner but I thought this is interesting, especially since a lot of people thought/and still think the Wii will fail. There doing pretty good, those numbers will equal 3rd part support.

"The site just updated the stats for the past week ending August 11th. The Nintendo Wii scored some major gains and is now breathing down the Xbox 360's neck. New data shows that in a frame of one week, 310,000 Wii's got new owners - Xbox 360 was sold in decent 110.000 units, while PS3 sold only 50,000 units. New numbers keep Xbox 360 in the lead with 10.43 million, Wii is now a close second with 10.41 million and PS3 remains the backmarker with 4.16 million consoles sold.
In terms of market share, Microsoft has 41.7%, Nintendo has 41.6%, while Sony captured just 16.6%."
