Overpriced by what measure? Medium format bodies command nearly a ten-fold increase in price over DX sensor cameras. FX bodies are not even a 2x increase. I find the D800 to be an exceptional bargain as it competes favorably with the Pentax 645D which is a $10k camera and the bargain entry into medium format digital.
