I went through your whole Q&A procedure and all my answers were ... Nope...
OK, except for the question No. 2. I very rarely print big pictures 100×150 cm, but they are absolutely great, both from D200 and D700.
I was VERY tempted to run to the store and get a new D800, but i fortunately skipped this step. Instead I jumped directly into your next morning and bought a new 70-200 f/4 VR III instead.
I couldn't do better! A couple of days later a friend of mine came to visit me with his D800 and 70-200 f/2.8 VR II. We compared the lenses and I found the pictures from my new zoom absolutely stunning. I am using it for travel and I believe it is great travel zoom.
So, enjoy your faithful D700 (it is still a great camera) and new 70-200 zoom and better improve your skills, what is exactly what I am going to do in the future.
