We know that the Nintendo Revolution won't be pumping HD - Nintendo has admitted as much. However, here's some interesting speculation from Falafelkid as to what they will be doing - better graphical results using a technique called displacement mapping. Rather than try to quote segments here, I reommend that you head over there and read it. The upshot - games like "Call of Duty" might look almost as nice on the Revolution as they do on the XBox 360.
