No its more the two areas in question. Japan and US are not the ps3's strongest area. Take Singstar for instance, that sells millions somehow. It's strong brand in Europe. Halo and Gears are both american centric as well, though I'm sure Halo manages a million or so in europe, just nothing like in the US.
The chart probably misses a whole lot of milllions from europe, like god of war; take even GT5 for example... etc
It would have been nice to have European numbers...
edit: of the top of my head
prologue shipped 5 million
Uncharted 1 and 2 near 8 million
Resistance 1 at least 2 million
resistance 2 at least 2 million
Lbp at least 2 million
Heavy Rain at least a million
Motorstorm at least 2 million
Motorstorm 2 at least a million
God of war 3 at least 2 million
Kz2 at least a million
Ratchet and Clank (both titles combined) at least 2 million
Socom etc etc etc
edit: problem being that we don't have solid numbers most of these...
