A "huge new PS3 exclusive" will be unveiled on GTTV this Thursday, according to host Geoff Keighley.
He took to Twitter to tell followers this "will be a good week for PS fans", adding: "Thurs on GTTV we are unveiling a huge new PS3 exclusive with first game footage.
"We had so much fun filming the episode and playing the game. I can't wait for everyone to see it."
Last week French site JeuxVideo also said it's to reveal a "major PS3 exclusive" in a live video show on May 2.
