4. Frostbite 2 Engine
This one is all but confirmed by DICE themselves. According to DICE, we'll "See this combination for sure." While Frostbite 2 doesn't look quite as good as CryEngine 3, the destruction and audio solutions are great and could work in a Mirror's Edge game. Imagine escaping from a building while it collapses, only to look out and see the sun flaring and police car lights flashing in your eyes, it would me amazing to say the least. Aside from all that, the character models the engine generates are quite impressive. Clothing is detailed and faces look don't look overly cartoon-like. We've already seen what Mirror's Edge in Frostbite 2 might look like, the Comrades level of BF3's single player was very much like ME's art.
