I think a lot depends on what Microsoft will announce at GDC and E3 as to how next year will go. This year compared to the last 2 years i think all consoles have a lesser amount of high profile games coming out. If MS come out with some big guns for the early next year i would not be surprised to see sales go even higher for january 2010 and beyond. The thing we know for sure is MS can sell the console cheaper and still make a profit so would expect that to happen at the end of 2009 again. If the financial crisis deepends as expected then that will play into MS hands as well.
The Wii is doing great also. Considering it is down so much in Japan it has space to improve further if things pick up there. Could be a great year for those 2.
Sony on the other hand is down across the board. A price cut will make a big difference for the PS3, would expect it to at least get back on par with last years sales.
