I do not see them lowering the price of the mkII in order to place the mkIII at the original price......
No, i see the price of the 5D2 being lowered to below £1500, maybe as low as £1300.
Why? Well, the 5D2 production line owes Canon absolutely nothing. Anything it is getting now is pure profit over and above. So, if it is still a crowd pleaser, why get rid of it?
How many times have we read people say 'they'd like a 5D2 but can only afford a 7d?'
And if the 5D3 sits around the £2200 mark on release, that is a huge extra outlay over a £1300 5D2. A win win all round for Canon. And once Canon get people onto FF, they then encourage the purchase of L lenses (even if it is the cheaper end of 17-40 f4L, 24-105 f4 ISL and 70-200 f4 ISL), not to mention external flash guns!
Almost every one wins
