Black OPs 2 on Wii U highly suggested to be 1080p @ 60FPS, best in class with better options too

[Barozi]

If Wii U could run BF3 in 1080p with 60FPS I would be impressed but this is not really a "significant" leap. Especially since the engine is incredibly old.
If they weren't so lazy and build another one from the ground up, they could improve their results even on old hardware by a lot.
