Lustful, but nothing I would need. And you know Nikon will surpass it, they always do.
Never seem more learned than the people you are with. Wear your learning like a pocket watch and keep it hidden. Do not pull it out to count the hours, but give the time when you are asked. --- Lord Chesterfield
$800 more than the Nikon D4, for 2 megapixels more.
I do understand the D1x has faster burst rate and has super fast focus so it is a great gun for the sports or BIF shooter.
Also, I have not seen a comparison of the video from the D4 and the D1x. With Canon having better history with video theirs is likely better but the video I have seen off the D4 is damn good. But, few on this forum are interested in video.
