Frostbite is currently a high grade engine that was developed by DICE for EA games. If BioWare, and EA company, uses the Frostbite engine, rather than the Unreal 3 or the new Unreal 4 engine, they no longer have to pay licensing fees to Epic Games for use of the Unreal Engine.

As a avid BF3 player, I am highly satisfied with the Frostbite 2 engine and have little doubt that a DA or ME game, once the engine is modified, would render great on it. As to how it would work, well that's another story.
