Nikon D800 Vs D4 - Hands on Comparison

I went Hands on with both cameras during my recent trip to Japan, at Nikon's office in Tokyo, and there's a question that needs asking, "Which one should I get, the D4 or the D800?", asking "which one is better the Nikon D4 or the Nikon D800?" is pointless, because they're both "better" at certain things, so let's break down what those are... and look at the new Video shooting "D-Movie" modes too.
