so u assume the console will sell 30M in NA and sell an additional 30M in PAL/Japan ?
do you know the actual sales ratio is already :
NA : 10
PAL : 5
Japan : 0.5
or the NA will purchase more Xbox360 to compensate the PAL/Japan sales
or ur prediction is dead
(I higly doubt the Xbox360 will increase her sales in PAL/Japan du to PS3)
(In NA all is possible)
Time to Work !
