By now the whole world know Nikon has launch their "affordable" D600 FULL-FRAME DSLR! Priced at US$ 2,099 (body) it is a thousand bucks cheaper than big brother the D800.
So what it is 12 MP LESS than the 36 MP big brother, who or how often do you need all those extra pixels anyway?
Every photographer worth his/her pixels knew the full-frame DSLR is the ultimate upgrade, trouble is a decade ago; you will have to take out a second mortgage just to upgrade to a full-frame system! It was that expensive ;)
