A BioWare spokesperson told IGN two unannounced games are being developed by two different BioWare teams. BioWare has a total of four teams at work currently. Though the spokesperson wouldn't reveal which games they are, both Microsoft Game Studios Executive Shane Kim and BioWare team members have said in the past that Jade Empire 2 (working title) is definitely in development.
We have two teams working on Xbox 360 titles, one team on Dragon Age (for the PC), and one on digital distribution, which is ongoing content created for Neverwinter Nights."
