Lets see, besides a good number of IPs that fans have been begging to see returned too (Jade Empire and Baldur's gate come to mind), they could easily create a new one series all together. After all, the all of their games that most people seem to love were all made in the last decade. Baldur's Gate? 1999, Neverwinter Nights? 2002, Swotor? 2003, Jade Empire? 2005, Mass Effect? 2007, Dragon Age? 2009.
If they can create that many hits within in a decade, I'm sure they can create another one with or without EA breathing down their necks. I also doubt a good majority of the people here are gonna swear off Bioware game, but call that just my intuition.
