I thought the PS3 would be doing a lot better this year (see my sig).
I have gradually come to the realization that there will not be a "breakthrough" in sales until the price gets below $300. No single game can help its cause right now.
I think my 360 and Wii predictions are almost on track, though...
My End of 2008 Hardware Predictions (console only):
Wii : 50 million
360: 28 million
PS3: 24 million
These predictions were made on January 3rd and won't be revised
