Does Microsoft need to release the nextbox 1 year before the competition?

Last gen:
PS2 120 million, Xbox 25 million

This gen:
PS3 60 million, X360 50 million

Next gen:
PS4 30 million, Xbox3 100 million

J/K. But yes, MS will use the trick of launching first again. Xbox 3 will outselll PS4 easily.
