I have been debating with myself what to do next as well. I have the D700 and D300 and it is a great combo. I have one set of batteries, can use the battery pack on both and get 8 fps for sports which I pretty much use the D700 for. D300 is for my wildlife shots or if I am shooting football. So Nikon has kind of gone off into directions where I dont know what to do. Need a D300 upgrade that is more pro level not the 7100 and I like the D800 except for the fps, takes away the ability to get great sequences in baseball. So I am stuck holding on to the D300 and D700. Which honestly I am still happy with the D700 it is the D300 that is getting old and pretty outdated. But I would like to see the true successor to both. It would be nice if Nikon would let us know some sort of intention because I am ready to pull the trigger on a new body, but for now it is just sit back and hope and wait.
