The wii sold in 2007 abt 15-16 million consoles not 19-20 million... soo lets not confuse the 2...
36-38 million wiis
19-20 million PS3(should do much better in NA, but not soo good in japan.. not enuf software for me)
24-25 million 360
83-88 million DS(all depends on japan, i believe it will start to decline there)
38-40 million PSP(If it doesnt launch any appealing software, it is doomed)
PS2???? cannot predict at all
