nice analysis, but just one thing.
Do you not account for a higher multiplatform ownership this gen than last? This would boost the "gaming population" and unlike other gens with many ports, this gen, the wii and the HD consoles have a very distinct offering.
(I say this but I myself had 3 consoles of last gen and only 2 of this gen... and i switched from US to EU so i'm totally off that trend :p)
