'Gamercard' spotted in UT3 demo – is this PS3's answer to the 360's Gamertag?

During a playable demo of Unreal Tournament III at the Edinburgh Interactive Festival, games-digest.com spotted something very interesting on the game's menu system. It's called Gamercard and it doesn't seem too unlikely a possibility that this will turn out to be a unique player identity system, not entirely dissimilar to the Xbox 360's Gamertag system that manages player stats and achievements.

Games-digest.com quizzed Epic's Mark Rein about and he did little to dispel our assumptions saying quickly "Oops, you shouldn't have seen that".
