Can PS3 Maintain its Lead in Software Sales for 2011

[DirtyP2002]

I don't think VGC is known for accurate software sales. They are an indication, but nothing to calculate on.
MS does not publish Xbox 360 software sales at all, so there is nothing to calculate from. It is basically guessed.

Another point is that Digital Sales became quite big on the Xbox 360, which is not tracked at all. Same for bundled download codes like we are seeing right now with Halo Reach.

I think the Xbox 360 will overtake the PS3 in this department, but overall it is a tie due to bad data.
