Mass Effect 3 announcement teased in the EA Vegas Games Show live blog

Apparently a presentation of Mass Effect 3 with a special announcement was made today at the EA Vegas Games Show, but thanks to a news embargo placed by EA, no one in-the-know is allowed to publish anything about it yet. EA Live Blogger Andy Katkin was mostly tight lipped about it, but he mentioned that it is an "exciting announcement" and that we'll find out within this week.
