Nost were very favorable about the 1D X too (and 1D X II and now 1D X III, what exactly is your point? The D4 was ok with high speed rate and tracking , that is why it was... a sports camera. And of course build and battery time.

Why would sports photographers need more DR? I don't get what you are trying to get at...

   You really have such a true insite into the role of the D4 BC ..... a high speed rate and tracking  ..... with build and battery time .... you know what? .... now you come to mention it I think you're right ...... it sounds exactly like a sports camera ....... ...... well fancy that ?? ........... who would have thought it ??? ............. 
 
 ........ In spite of your positive identification of it's role within society there still rests several "non comprendo" moments for you ....... which seems a little strange ....... so, I'll put it in it's simplest form:
 

 ....... the DF/D4 had a very good sensor  !! .......

...... if necessary, let me know what part of that sentence you didn't get and when I get time we can run through it together .........
