I know people who used to work there. It's been dead inside for quite a while, and it wasn't really EA that killed it. Bad management, mainly - they fought over turf and they constantly changed their minds about what sort of game was being made. There were basically two teams inside BioWare, the Dragon Age team and the Mass Effect team, and neither liked the other (at the management level that is - the coders and designers and testers down in the trenches were just their cannon fodder and got on fine).

After all the cuts the studio has suffered for the past few years, all the cannon fodder was already gone. The only people that were left inside that shell of a studio were the managers who had been fighting over it. The "winners" got to go down with the ship that they'd won.
