The 5DIII was supposed to be a top of the line camera. The 6DII is an upgrade to the entry-level 6D.
The 6DII has a boatload of upgrades compared to the 6D.
The one point you guys are picking on is a minute (0.2 stops) at 1 ISO setting. That hardly makes it a POS.
Much worse was said about the: 60D, 6D, 7D, 7DII. I really don't think anyone who would seriously consider a 6DII would be bothered by 0.2 stops at 1 ISO setting. Much ado about nothing.
Interestingly this is from somebody that loves the 80D for the past year, which kills the 6D2 in the low ISO shadow noise area, yet you think it is okay to have not put the new sensor into a new 2017 camera? It isn't really about the 6D2 vs 6D, that is just a litmus test, it is that any current generation FF sensor should beat the same APS-C sensor in DR and ISO, however the 6D2 doesn't do that. That is the crux of the issue more than the fact that the 6D2 is actually a bit worse than the 6D. This is the FIRST time Canon has pulled this on the consumer base, and it has some frustrated and a bit worried as well.
Also when the 6D came out, there actually was hardly any complaints about it other than its Rebel-esque build. In fact, 6D owners flaunted the fact that the 6D was cleaner in the shadows and had better high ISO over the 5D3 owners. I lived through that era, you weren't even on the boards back then. I had a 6D and a 5D3, and decided to stay with the 5D3, despite all the posts rolling around on the 2.
