Ok, I'm at a bit of a loss here. The D800 is solid. The 36mp thing is annoying and ridiculous, but it's hard to ignore the fact that at least on paper, the two cameras are EXTREMELY similar. Pros for the D4 - New memory card format - Ethernet - 11fps (if you need that... I don't) - 1 click better ISO than D800 Pros for the D800 - USB3 - 36mp (if you need that... I don't) - $3,000 LESS! That $3K is a lot of cash... I could buy some accessories and the remaining lens to fill out the holy trinity. Hard to ignore. I keep thinking "well, gee, the photosite sensor size on the D4 is like 60% bigger... that's going to translate to better image quality"... but in truth, I have no way of knowing that. Any thoughts? I'd love to hear them.
