Remember that Best does not necessarily mean Most Expensive. I'd keep an eye on reviews from DXOmark and (bite my tongue) Ken Rockwell. Don't forget Third Party mfgrs. like Tamron and Sigma Art lenses which have really come a very long way...
A good friend of mine upgraded to a D800 a while back and became frustrated quickly. He had to upgrade his glass substantially to take advantage of the increased resolution. I'm sure when they 5Ds/r is released you will see that the flaws will be magnified with inferior glass.
