I believe in 10 year. Not because of any plan, but because Sony cannot afford to ship a new console for at least 4-5 more years. The financial burden is just too great.
So they are stuck with the PS3 for a very long time. Planned on not.
Prediction made on 11/1/2008:
Q4 2008: 27M xbox LTD, 20M PS3 LTD . 2009 sales: 11M xbox, 9M PS3
