I've come to similar conclusions. I actualy ordered a D600 on Amazon moments after I heard the news. Within a couple of hours after thinking about it, I canceled my order. At this moment I really could not justify the purchase. I do weddings every now and then and the D700 and D300 I have as a backup suit me quite well. It would be nice to have that extra pixel count and dual SD slots but I'll just have to wait. I can possibly raise half the money by selling my D300(8000 actuations) and my 18-200 DX VR. I'll wait and see. Looking forward to seeing some nice samples first.
