I may do one per publisher later, which should also be interesting.

Software sales in 2007 vs 2008 per console:

Console	07 holiday SW sales (7 weeks)	08 holiday SW sales (7 weeks)	Change
Wii	30,939,985	54,345,896	+75%
DS	36,432,415	48,158,579	+32%
X360	26,573,939	41,474,349	+56%
PS3	13,537,954	23,845,445	+76%
PS2	19,594,390	10,664,233	-46%
PSP	7,895,488	6,559,768	-17%

 

I can't believe the difference between DS and PSP! How can that be?? Why arent PSP owners buy games (apart from some piracy)?
