"Gran Turismo 5 is going to sell double that easily. KZ2 and GoW3 will easily cross 4 million, maybe 5 million. Heavy Rain and inFamous won't sell very well, but they will both be very good games."
To this date
GT 4 sold 9.5 million world wide
KZ 1 sold 1.5 million or so
God of War 2 sold 2.33 million
Your numbers need some major adjusting.
