to me 5d2 in a lil bit pimped body n price in sub $2000 would make it hell of a re-birth ...
Hmmm, i believe that Nikon will use an already existing (exactly the same D3X ) sensor due to the final product price tag. If the rumors are correct a $1500-1800 is a very low price for a FF camera with those specs.
In my opinion investing in a new sensor for a quite low price camera is unlikely. More reasonable is to use an already researched and tested ( cheap to produce due to the already existing instruments) sensor.
