I am kind of in the same boat. I am slowly trying to convince myself to wait for a mk3 upgrade just to get a mk2 at a discounted price. The mk2 is an incredible camera, and it overly capable. I suppose it depends on if you need what the 5dmk2 has to offer, or just want the best of the best. Keep in mind however that the mk3 has been highly rumored for a while now, nobody is quite sure when it will turn up yet. I would hold out until after Photokina and see what turns up, after that I would let desperation get the best of me... []
