Not really, in two years the D5s will be an updated version of the D5 so nothing shockingly new.
A D5x would please some members here I guess as the only way to go high res with Nikon is the D810 and I know some prefer the single digit bodies for serious outdoor work. Compared to the Sony and Canon offerings the 36MP is not that high anymore however so it needs to be at least be 42 or 50MP for Nikon to excel in the MP race (they seem to have won the ISO race for now).
