For me personally, the question is:
Will the rumored (http://www.techtoyreviews.com/canon-5ds-image-leaked-price-tag-3800/) 3800$ (5DS) or the 4300$ (5DsR) be worth the price, Canon will want to have for it?
Or wait for an 5DIV, an goldenegglayingwoolmilksaw??? But how much will this be?
Those prices are way too high. If true, Canon killed the success of this camera right out the door. It can't be more than the D810. If anything it needs to be less, as most people looking for higher MP and higher DR have already moved to Nikon. I doubt many people are going to pay more for something with just more MP. 36MP is already taxing out many lenses and is a huge amount of detail!
I can't even think of a single professional landscape photographer who hasn't moved on to an A7R or D800/810 by now, who shoots with 35mm format gear.
Sir, I am just an hobby photographer, but why shouldn´t Canon drain our wallet as much they can?
Look at Apple, whose iPhones are just incremental better than the earlier model? But on each sucessor, the price moves up and up....
Edit: My son in law mentioned, that the a7rII (successor) will be priced significantly lower than 3000Euro, at 2500+-. As many parts of the camera-systems are better from Canon, the pricetag could be true
