MikeB - but your assuming that just because a genre of games eventually will give the PS3 parity.
It won't.
We saw time and time again last generation, when a given system built up a strong userbase of owners that enjoyed specific genres of games, they sold much better. Platformers sold better on the GC (mostly), Shooters on the Xbox, and everything else on the PS2.
The Xbox 360 is building a strong userbase (see this years sales in the US vs. every other year) for these type games. Because of this, when the PS3 has a somewhat decent userbase in the US, the games won't sell. Go look at the GTA series. By the time the games, although certainly oriented to the Xbox userbase, failed to sell on the Xbox as well (per the installed base) because GTA's userbase was vastly stronger on the PS2, because the series had been there longer, and better.
Each genre will be this way. The X360 has vastly more WRPGs on it than the PS3. Because of this, WRPGs will sell vastly better on the X360 vs. the PS3, regardless. Fallout, Deus Ex, and others will see much smaller sales, because the userbase won't be as developed on the PS3 as the X360, since games like Oblivion, Two Worlds, Mass Effect and such were there, were earlier, and helped build up a much stronger WRPG base than the PS3, or Wii.
Back from the dead, I'm afraid.
