I always love the DigitalRev guy. Funny, quirky, bit of a bikini-clad woman -izer, er...chaser...

I also think he straddles the Nikon/Canon fence well in his comparisons, although he does tend to be Nikon-biased.
As for the video and the results...near the end, when he was shooting in low light, two things caught my attention. For one, the 5D III seems to have FAR better color!! The D800 appeared very washed out and kind of dull, but the 5D III color was brilliant! When he made his comments about sharpness I became a bit curious. Both images were downscaled to fit into a 1080p video...NEITHER of them should have really shown any difference in sharpness with that much downscaling, yet the 5D III did appear a touch "soft". I wonder if that was a bit of "Nikon-biased" editing? I've seen other sample 5D III shots that are tack sharp, regardless of the fact that they are lower res than D800 shots....eh, curious, curious.
