Uncharted 2, Demon's Souls, Ratchet and Clank: A Crank in Time, Modern Warfare 2, White Knight Chronicles, Bioshock 2, Ninja Gaiden Sigma 2, Assassins Creed 2 (even though I passes on the first one) all for PS3. Some of these may slip to winter-new year due to money and time. I'll pick-up a couple of DS games too.

Tekken 6 , MW2, R&C ACiT , Bioshock 2 , Uncharted 2 !!! , Oh and of course GT5 if it's released

Uncharted 2
Modern Warfare 2
Red Dead Redemption
GT5 if it releases

TMNT: Smash Up, Zelda: Spirit Tracks, New Super Mario Bros. Wii, probably Red Steel 2 (either that, or Tatsunoko vs Capcom, or Phantasy Star 0. That's the tough decision right there)

ps3:
BioShock 2
Uncharted 2
Modern Warfare 2
Fallout 3 GOTY Edition
Gran Turismo 5 (but i don't think it will be released this year)
Demon Souls
White Knight Chronicles
Demon Souls
Tekken 6
