According to the Dragon Age 3 press release, which came September 2012, EA claimed the game would be running on Frostbite 2. Later, in a November 2012 blog post, BioWare studio director Yanick Roy mentioned that Dragon Age 3 used Frostbite technology “as its foundation,” but did not specifically say Frostbite 2.
So all that impressive stuff you saw in the Battlefield 4 reveal? Try to imagine how it might shape the next Mass Effect and Dragon Age titles.
