"But 100,000 people left Sony for Microsoft this week, and as many as 300,000 left Sony for Nintendo."
FAILED! for more than one reason.
1) The original Xbox sold around 25 million units. Until the 360 passes that mark, it's safe to assume that the vast majority of 360 sales are REPEAT customers.
2) The Wii has outsold the Gamecube so maybe some of them are PS2 owners. However, it's well known that the Wii has hit a new demographic. Older people, families, and in general, people who are NOT gamers are buying the Wii for the casual family fun party appeal that it has. A huge portion of the Wii sales were from people who didn't even own a console last gen.
VGchartz STILL shows that the PS3 sales are matched day and date with PS2 sales. Until that changes, the Playstation userbase HAS NOT DIMINISHED.
