I'm conflicted, but I think I have a plan.
At some point I want to have 3 bodies, 2 for weddings, and 1 for personal/backup.
D800E's are too expensive for me at the moment as I would have to buy 2.
Also ideally I want to shed some weight, as carrying all that weight for 10+ hours at a wedding begins to take it's toll.
So I'm thinking of trading in my D700's for D600's (pending reviews), to use for weddings. And then saving up for a while to get a D800E. I plan to use the D800E for landscapes and studio type photography. If I drop the D800 in the sea, it doesn't mess up my wedding business at the weekend.
I'm looking forward to the D600, as I remember how much I liked the D7000. With a grip, I actually much preferred it's form factor over the D700, but the only thing missing was full frame.
