That is an insane back ! and when coupled with High end glass you just stare in dis - belief. I shoot with a Sinar 54M / Schnieder 40/3.5 at ISO 40 and the 22 mp images are of amazing quality..Of course it is a HUGE pain to shoot with and 90% of my work is with a D2Xs where 12mp is more than enough. I know your comment was somewhat in jest, but I wouldnt count on the D4X even coming close to the 22mp digital back - I think its more about Pixel and Glass Quality than about MP count. Match a Sinaron or Rodenstock lens to a Digital Back and I just think the image quality is beyond Nikon Glass.
BUT as I said....90% of the time I grab my trusty Nikon !
