The simple physics is that if the FF sensor is 50% longer than the APSC sensor in both dimensions, the FF lens only needs to provide 2/3 the resolution of the APSC lens to match the overall system resolution. If the FF lens approaches the quality of the APSC lens, then a near doubling of system resolution can be achieved. What this means in real world terms is that you dont need "super world class" lenses on FF to get great results, unlike with APCS sized sensors.
JC, consider this: 36 MP of Nikon D800 is more than twice the 16 MP of Pentax K-5 or Nikon D7000. Therefore your FF Nikkors ought to be as good as they are on your APS-C D7000 in terms of spatial resolution.
Consider further, that it stands to reason that the next generation of FF sensors will have even more pixels in them. I vaguely (sorry :-( ) recall rumors of next Canon FF DSLR flagship having in excess of 40 MP. Therefore on FF your lenses actually have to be even better in this regard than they were on current APS-C cameras.
So in theory you're right, but it would seem to me that technology would soon enough overtake your theory, in a manner of speaking.
