With only a little over a week until March 2, the specs from leaks will firm up. The NL rumored specs are exactly what I have been anticipating, similar sensor, 1/2 - 1 stop better high ISO in raw(something I implied from the jpeg rating of 25600), and better autofocus.
If Canon is going to stick to the same original price of $2800, we are not going to see a revolution, more like a FF 7D set of features.
I'd order one immediately, merely because I can't justify a 1DX.
