Are MS playing their cards right though? GTA is out and hasn't shifted tons of units for any platform, despite expectations it would, while PS3 has crept up to match XB360 sales. At current trends, PS3 is growing faster in all markets than XB360 and will slowly overtake. Why aren't MS turning early lead into snowballing growth? That's what's supposed to happen, and AFAIK the theory behind the 'first to 10 million consoles wins'. That install base is supposed to drive interest and more sales. Is it just a matter of Wii upturning everything, and if not for Wii XB360 would be selling that strongly?
All markets besides US. Only 2 of 18 months did it beat 360 and only by a few thousand units at that.
