Well, I expect a huge effect because it is NA where the Xbox360 is very strong.
Xbox360 will pass PS3 WW again during september/october but I see the PS3 coming back WW at the end of october.
The only possibility for MS is to shift from hardcore to casual in 2 months to better fight the Wii. Then they may win the whole rest of the year.
I doubt they will succeed.
Time to Work !
