Bioware is counting down

A mysterious countdown has appeared on Bioware's official site, which - according to Gamereactor's hired mathematical geniuses (I am not one of them) - will reach zero on Monday evening. No clue what it is counting down for, since that'd be spoiling I guess, but the same counter can be found on the websites for both {Mass Effect 2} and {Dragon Age: Origins}.

No counter on {Star Wars: The Old Republic}, so stop dreaming about that beta invite. Could it be a new expansion pack for {Mass Effect 2}? Mass Effect 2: The Ferelden Initiative? Dragon Age: Space Hamster Invasion? I can do this all day.
