This is really one of those "a rose by any other name would smell as sweet" cases, but Electronic Arts confirmed to Gamasutra that their EA2D studio has become a part of BioWare and is now called BioWare San Francisco. This is not the first time something like this happens (you may remember how Mythic became BioWare Mythic) and is apparently a part of a bigger executive and studio shuffle going on at the juggernaut publisher.
EA2D is responsible, among other things, for the Facebook title Dragon Age Legends.
