Well, I'm definitely enjoying this thread. Lots of mini-meltdowns. Anyway, a couple points:
The first year is always the "make or break" year for a console. I can't think of any example where a console sold either really well or really poorly the first year, then suddenly had its fortunes reversed the next. The best example I can think of is the DS, but that was because of software that opened it up to a whole new market, which leads me to point 2:
None of these games will do anything more than a temporary bump in sales. That's just how sequels work. It's the same reason a new Mario or Zelda doesn't push Nintendo's hardware anymore. It's the games that come out of nowhere that are the real system sellers. Stuff like GTAIII, Halo, Brain Age, Wii Sports. Fresh software that draws new audiences in, that's what pushes hardware. Unless it's a sequel that completely redefines a franchise (FFVII, GTAIII), and even then, it doesn't always help (OoT, RE4). Also, you don't get to say KZ2 is a system seller before it's out, especially after you should have learned your lesson with the first game.
I think a lot of you need to give up on the dream that the PS3 is going to suddenly blast through the stratosphere and follow in the PS2's legacy. It's probably not going to happen. I know it's hard after getting used to being the undisputed champion for so long, but you have to let go.
