Due to the "no camera" rules there is no photographic evidence, but we're still happy to commence the speculation. Especially since Mark was so secretive about it. Is it a UT3 feature? Is it Sony's answer to the 360's Gamertag? We're not sure, but we'd definitely like to know. No doubt we'll hear more before the release of Unreal Tournament 3, at least. We'll try and contact Mark for a statement, but expect him to remain extremely tight lipped. What do you suspect it could be?
