Games Digest may have 
caught a glimpse of a Gamercard feature similar to what the Xbox 360 has when they were demoing 
Unreal Tournament 3. It was suppose to be hidden as Mark Rein of Epic said that no one was suppose to see that. Since no cameras were available, there's no physical evidence so we'll keep this in the heavy rumor bit for now but that'll be an interesting little addition if indeed the PlayStation 3 is getting a Gamercard feature. Then again, this could just be 
UT3 specific.
