I don't think it will be amazing for a 2012 camera. Maybe it would have been if introduced 2-3 years ago. Basically Canon will have a camera that is roughly competitive with the D4, and the D3s was years ahead already in just about everything but resolution.
I think 1D X is an amazing camera for 2012. There is no competitor. What else would you have expected? If rumors come true, Nikon will have a D4 within some weeks or month that might be roughly competitive (except two stops less "native" ISO at 2MP less resolution). Some guys from the Nikon side expect, it will be as expensive as 1D X - or maybe some 100s $ more. As far as I see, not much has changed compared to D3s - except they now offer a 3 year old consumer bodys standard in resolution now. In my opinion (YES, I am a Canon fanboy ) 3Ds was just the try of an neccesary upgrade to make Nikons 3D flaggship competitive somehow.
