Some points I want to make for the establishment of my own context though - and I do understand where your general frustration would lie by the way, don't want it to seem otherwise as we discuss!
Ok well firstly, like I mentioned, I myself know some folk whom hearing it from me was the first they'd heard about the game, and they are themselves PS3 owners. But that's neither here nor there per se. One of them owns R1 and R2 alone, and the other owns EoJ and Disgaea 3 alone, with an interest in Valkyria. Both use it primarily for BD.
There are better games than KZ2, absolutely. That said, remember I myself don't think that the games sales are bad at all - I think they're quite decent in the larger picture. But, they are not the world-changer some thought they would be. I was never one of those people, so I could just as readily be arguing the other side of this thing, it's just that I do think in terms of achieving maximum effect, Sony actually did some things that ultimately detracted rather than added to the sales.
The front-loaded hype was one of those in my book, and I think Christmas would have been a better fit across from Gears. Now we'll never know if I'm right on this or not because time marches on, but I just want to clarify that when I present these theories, it's not in the sense of a world in which KZ2 would have been reaching those multi-M sales numbers, just some missteps I felt occurred on Sony's part.
