well, this is particularly MS that is affected by the Wii sales
Remember with the Xbox360arcade they are targeting the same crowd
because of the wii, the Xbox360 has some problem to totally reach the mass market
which "cheap" console a casual will buy ?
1/ Wii
2/ PS2
3/ Xbox360 arcade (or 2/ if he has a PS2)
Nintendo is severely damaging MS
Time to Work !
