What Is BioWare Counting Down To?S

A mysterious countdown timer has appeared on BioWare's home page, as well as the pages for Dragon Age: Origins and Mass Effect 2. What is BioWare revealing on Monday?

Kotakuite Alexander pointed us to the countdown clock that's now ticking down the days, hours, minutes, and seconds until Monday morning at noon Eastern time, 9AM Pacific across most of BioWare's current web presence. I say most, because while the timer is indeed on BioWare's main, Mass Effect, and Dragon Age pages, it does not appear on the page for Star Wars: The Old Republic, which leads me to believe the reveal has nothing to do with that game in particular.

With the Dragon Age: Origins - Awakening expansion pack was recently released, and Mass Effect 2's Kasumi downloadable content coming in April, what could the developer possibly have up its sleeve for Monday, March 29? A new game? More downloadable content? A version of Mass Effect 2 that isn't for the Xbox 360 or PC?

It's time for rampant speculation. You folks know what to do.
