In my previous life, I was using Canon cameras and I did experience the same thing when I upgraded from an 8mpix camera like the 1D II to the 1DS III at 21 mpix. My full frame shots were, all things being equal, less sharp. Then you work on your technique to adapt.
I now have 2 D800e and 0 Canon, and I am used to this kind of trade off and and I manage. I guess other users will get used to it as well.
