First of all kowen, it isn't 400k for december it was less than that. I love how you take the low end estimates to suit your needs when more than likely it was mid range (and gamesutra says 635k) which would be 365k-37k over tracked.
Secondly I know why ethomaz thought it was overtracked in December. It's because he thinks in ps3 vs 360 a lot. And in December 360 was overtracked more than the ps3 was. Thus the Ps3 actually gained ground on the 360 even though it was overtracked
