Nintendo aren't expecting more than 12m this holiday Q, judging by their FY forecast (18m) (which they rarely ever hit anyway, FACT)
So we have
3DS: 16m
WiiU: 5m
Wii: 1.5m
DS: 0.5m??
PS4: 3.5m
PS3: 10m
PSP: 2.5m?
PSV: 3m?
Totals
Nintendo: 23m~
Sony: 19m~
Numbers could sway either way for any console, but it's not a runaway win for either.
Forgot I was doing full year 3DS sales not holiday, so I stand by Nintendo winning!
3DS = Sony combined is absurd tho.
