^I did answer your question Sony can claim the PS3 for ten years all it wants, it won't sell that long people won't support a third place console for that long, inevitable to pass the 360, sorry no, its possible but not likely.
As for any people remaining to buy from the last gen, those are likely people waiting for lower prices, as they are those who bought at the tail end of the last gen, and those consumers will likely got the 360 or Wii, not the PS3, as the PS3 will be more expensive than the 360 (since MS will price cut next year and Sony will be hesitant to do so due to the losses on the PS3) and won't have the games of the Wii.
Predictions:Sales of Wii Fit will surpass the combined sales of the Grand Theft Auto franchiseLifetime sales of Wii will surpass the combined sales of the entire Playstation family of consoles by 12/31/2015 Wii hardware sales will surpass the total hardware sales of the PS2 by 12/31/2010 Wii will have 50% marketshare or more by the end of 2008 (I was wrong!! It was a little over 48% only)Wii will surpass 45 Million in lifetime sales by the end of 2008 (I was wrong!! Nintendo Financials showed it fell slightly short of 45 million shipped by end of 2008)Wii will surpass 80 Million in lifetime sales by the end of 2009 (I was wrong!! Wii didn't even get to 70 Million)
