About the PS3 games,
the only system seller u have truly have to take in count for the moment is
GT5
about the others games :
FFXIII : not 2008 WW
KZ2 : hyped but too hardcore and maybe too classic at the end
Resistance 2 : hum, maybe the good surprise of this year
GT4 : THE BIG ONE but multiplateform
MGS4 : a bit too hardcore
EIDT: GT5 may only be release WW in 09 in fact ...
Time to Work !
