Gran Turismo 5 to sell over 15 Million LTD or only over 10?

[ZorroX]

^ What wow effect had Halo 3? GTA 4?
Anyway, in 5 weeks FFXIII will be released, though Uncharted 2 sales already showing some positive signs.
And MGS4 won`t stop selling. It will be over 5M next year.
GT5 will sell over 1M in Japan, maybe 2M+.
