I've changed positions and now consider myself very likely to upgrade to the 6D once my tax return is back next year. I think it really does present a good value. the FF sensor is a huge step up, the high ISO is very helpful, and although the focusing system as a whole may not excite a lot of people -3 EV center point should be very valuable to me. Hopefully the price will drop a bit by that time next year too!
