"60 frames-per-second and latency on the controls still as important as ever and what separates Call of Duty from others"

I still don't get why they are so fixated on 60 FPS. Unreal Tournament 3 can run with more than 100 FPS, if you have the appropriate hardware. Metal Gear Solid in HD version and Golden Eye Reloaded both have 60 FPS, so I doubt that it separates CoD from others. CoD can be unique in it's own ways.
