@tombi: Still, PS3 would be the most expensive console, of course sales will increase because of people wanting a PS3 for a cheaper price. I believe that MS will not cut the price even further, but Sony may and still they will be head to head. 360 may sell less than this year, after all, this pricecut came in raelly handy because the holiday season was just starting, next year I don't see many people going crazy just to get a 360. Sales will definitely be smaller for the 360 in 09.
PS3 will still be more expensive than its direct HD competitor and than the Wii which is the preferred console among most gamers.
