You're right, John. Adaptation of R lenses to a F body is impossible but you can modify a F body to fit the R lens.
I won't get too excited about these new Nikons, think about it ... Canon will only need to release the 5D upgrade ...
16MP FF CMOS
6-9fps
ISO 50-6400
14 bit A/D
45 AF points with 19 cross type sensors
Then all Nikons will become dead fishes again. It's a friendly competition between these companies, Nikon needs a break ... and Canon gives.
