No I'm not a typical consumer I work for one of the largest sports agencies in the world. I would be replacing 24 kits and for us that's 56 bodies and their associated glass.We're not "typical consumers" and many were willing to do 20MP for the other benefits; in fact many found that a positive benefit.
Whether A) your attitude is typical in the 1-series customer base (maybe most disagree with you) and B) Canon recognizes this, will make a marked difference in what happens.
There is (are) no benefit(s) of a governed or limited 20MP that cannot be adjusted while shooting.
This technology has been in camera since the 1DX and its very simple to shoot at a reduced file size in RAW and JPG. This 20MP, straw dog or red harring is played out. If someone wants to shoot at 20MP let them perhaps they want to shoot at 8MP, let them. But there is no reason to limit the resolution any longer, that thinking and technology was even in the original 1DX in 2011/2
One has to wonder why people don't look at A1, R5, Nikon z, and even the 1DXMKIII and realize decreasing file size is eazy on "the buffer" ROFL.
It's about time our industry matured with equipment that is comprehensive.
