Get ready for $2500 MSRP .
A $2500 MSRP would mean a €2500 MSRP price in Europe. That would be a NON-competitive price. For 400 euro more, you can get the 5D MKIII. It just does not make sense unless it is the opening price that needs to go down with at least 600 euro but only after 4 to 6 months. By then, most may have saved the money to buy the 5D MKIII
5D3 is $3500 MSRP, regardless of the actual retail prices. I think it is logical to assume that the retail price of this rumored poor-man's 5D would be lower than it's MSRP as well. The old 5D2 is $2200 MSRP, but you can get it for $1899 from amazon (atm). If 6D was $2000 MSRP and even lower retail price, then who is going to buy either 5D3 or 7D2 (which should be near $1900 MSRP) ?? Not me!
Currently, the only reason to buy a 7D over a 60D or 5D2 is for the speed, AF, etc. for sports shooting... and those benefits will still exist over this alleged 6D. So (as I said above) I see it the other way around... who will buy the 6D over a 5D3 or 7D? Yes of course some will buy it... if you don't shoot sports, and don't need the advanced features of a 5D3, and understand the IQ advantage of FF over a crop (eg. 60/650D)... then this 6D is perfect... but how many consumers fit into that category? You do, and so do many people on this site.... but that is a small slice of the market Canon needs to hit to make decent sales volume.
