I have committed myself bigtime. I have just put my Nikon D800 and full frame stuff on the block. If anyone is interested in some uber-resolved (36MP on full frame) sensor and supporting glass and light, let me know and I will point you to my ads. The bottom line is that I have decided to give up full frame and concentrate on Mu 4/3. I'll keep my APS-C IR-modified Nikon, but no other big sensors for me. It just causes too much weight and volume - and that is no fun when globe-trotting. I hope I don't regret this and if it doesn't sell really quickly, I may take the big stuff with me to Colorado next week, but I don't relish the thought.
