Got to say, despite any high hopes Sony (or others) might have had, KZ2 was always going to struggle in USA.
Most of it's potential audience was already committed to another platform, and even if KZ2 had been the best FPS ever (which it wasn't, although it's very, very good) it would have failed to sell better.
On paper, given the fact KZ2 is a very good FPS, you'd expect it to be on 4 or 5 Million. But that would need a far greater adoption in US.
It's interesting to note that on PS3, many FPS and similar titles seem to sell roughly the same in Us and Others. On 360, FPS and similar titles sell way more in US relative to Others sales.
And that skew will always (unless PS3 really starts to hit home in US) hold back big FPS on PS3.
Try to be reasonable... its easier than you think...
