Heh, this is a funny thread. No systems have many dates for games in 2008 because it's in...2008. As we get closer to E3 we'll find out a lot more about future games, especially now that it's May when E3 used to be. There will be plenty of games on all of the systems.
Btw, I would not be surprised at all to see Bioshock and Mass Effect on the PS3 at some point. Reminds me of GTA on the PS2 and the eventual released on the xbox. A Trilogy is a long time to not branch out.
Does anyone know how involved Microsoft Studios is with Too Human? I know it's being developed by Silicon Knights, which according to wikipedia is still partially owned by Nintendo (stock holder). I know Microsoft Studios is publishing Mass Effect but Bioware is still independant and developing games for other systems (including the PS3), so I'm curious about Silicon Knights.
Anyway, why don't we wait until E3 before we judge 2008? People try to get so ahead of themselves...
