p.4 #1 · Crop sensor vs. full - reverse calculations?
cicopo, using the same lens and taking into account the 2.56 (1.6x1.6) factor, the 36.3MP D800e cropped to match the 7D image would be 14.2MP compared to the 7D's 18.0MP. That is a minor loss in pixels if I am gaining 2 stops in ISO setting (for about the same noise), 2 to nearly 3 stops DR and better AF. It is a tough decision given that I am heavily invested in Canon, but if I was starting fresh and looking to make a decision, at this point I think it would be an easy one.
I owned Nikon many years ago and went digital with Canon in 2003. I don't really feel any undieing loyalty to either. I do have a tough decision in front of me though.
p.4 #2 · Crop sensor vs. full - reverse calculations?
Canon and Nikon seem to leapfrog eachother over the years. I would say stick with Canon for now. If you are that heavily invested into Canon, switching to Nikon might cost you a lot more than an upgrade to a supertele which seems to be the correct path based on your experiences.

RogerC11, I would normally agree with you, but Nikon has leapfrogged Canon on the MP while if anything extended their lead in noise management. The 7D is over three years old and there aren't even any industry rumours of a replacement for it. Being that old and Christmas on the doorstep, one would have thought something would be eminent.
I am willing to wait a bit, as I am also interested to see what Sigma is doing with their new 120-300 2.8. If it is an improvement over what is apparently already a pretty good lens and I take into account that I was already prepared to spend on a new body, the switch could be quite reasonable financially.
At some point I have to chose one of the forks in the road and just go.
