From ThreeSpeech.com:
We got the low down from Sony and the confirmed title list (so far) is as follows:
PS3
GT5 Prologue - playable code
Everybody’s Golf: World Tour - playable code
Time Crisis - playable code
Echochrome - playable code
Killzone 2 - trailer
LittleBigPlanet - trailer
Play TV - trailer
PSP
God of War: Chains of Olympus - playable code
Should be a good one!
I hope the LBP and KZ2 trailers are new! *crosses fingers*
