BioWare has released a random countdown clock today on their official website as well as on the sites for Mass Effect 2 and Dragon Age: Origins. This may very well count out the coming announcement being related to upcoming MMO Star Wars: The Old Republic, as the clock has not appeared on the game’s site.
In addition to the clock, a new slot has appeared in BioWare’s drop-down menu for the developer’s games. Under The Old Republic, there is a slot titled "New Next Gen Game". Whether or not the two are related will be revealed when the clock expires, which is currently set to 6:00 AM EST on Monday, March 29.
