Sony to unveil a new "Exclusive Playstation 3" game in a special event showcase the day after Spike's VGA show occurs.
So far its rumored to be Uncharted 3 (to be shown at the VGAs) or another game already announced in the past.
Unlikely it will be a brand new title or series but the odds are the game gets leaked before the event since Sony is horrible at keeping secrets.
