I would just remind you that the 6D Mk II price at launch should have surprised no one because it was in alignment with the introductory pricing of the original 6D and in particular the pricing/value relationship between the 5D Mk III and the 6D vs the 5D Mk IV and the 6D Mk II.
I think the greater issue for many (at least those that were anticipating the 6D Mk II performance/spec-wise, was that in certain tests the 6D's sensor performance bested the 5D Mk III (as the 6D came out after the 5D Mk III) and I think that fact loomed large in a lot of the anticipatory thinking concerning the 6D Mk II's sensor vs. the 5D Mk IV. Canon was not going to make that "happy accident" a second time. The other significant issue for Canon's latest DSLR offerings (in the past 3 years), at least according to various photo sites and forums, has been there seeming unwillingness to really embrace/adopt non-bastardized 4K in these models.
Sorry my post has gone a little rogue here (off-topic). One final statement. What is the number 1 cause of friction in any relationship? Whether inter-personal, or say between a customer and a business (of any kind)?
Answer:
Our expectations - of the other party/person, product, service, etc.
Example: Canon's 6D Mk II.
Does the 6d Mk II take great images? Does it work properly? ...? ...? etc.? By all accounts, from those that purchased it, YES.
Does it have short-comings? Yes
Has every camera model introduced over the last 80 years had short-comings (for the time it was introduced)? realistically. YES.
But some, even many, models have at least met, if not exceeded, EXPECTATIONS. Example: 5D, 5D Mk III, in some ways the 5D Mk II (think video), 1DX, F1, AE-1, T-90, EOS 620, (and these are just a few of Canon's models).
