This analyst expects Wii to take the sales previously expected from PS3. X-Box 360 sales expected to be steady.

 

Doug's revised estimates:

• Sony will sell about 4 million PS3s in 2009, down from previous projections of 6.25 million units sold. Fewer PS3 sales in 2010 too, now projecting 4.5 million units sold vs 6.5 million previously.
• Wii picks up the slack: 8 million consoles to be sold in 2009 vs 6 million previous. More in 2010 too: 6 million vs old estimates of 4 million.
• Little change to Microsoft's Xbox 360: Estimates fairly steady, Doug sees 4.25 million this year, and another 4 million in 2010.
