I think I'd reached a point on my 5D3 when the 5D4 came out at an incredibly expensive launch price, that I was done with Canon. The limited tiny incremental upgrades, the crippling, the holding back of features, pricing strategy, and what was obsolescent mirror technology made me think there was no point in buying mirrored cameras any more when they were so expensive, so big, but would be worth so little in relatively short order. The X-T2 cost me little more to buy than amount the 5D4 has depreciated. I'm back up size wise to full frame and I'm good with that as long as I can reduce the size for when I want to travel light. I think the size of the Sony means it can be both a serious FF camera, and a reasonably compact travel camera with superb quality. I'm not naive enough to think it won't depreciate more than the X-T2 costs, but it's cost me a lot less than the 5D4 would have done. (That's if I ignore the extra premium for the lenses....) I'd like the 70-200 2.8, but need to get over the size and weight of that or at least persuade myself I'll not leave it at home as often as I did with the Canon 2.8 II. In ideal world, I'd have an F4 for travel, and an F2.8 for everything else, but I don't use those Focal Lengths hugely, and I'm strictly amateur use now (I just like nice gear

) so both is out of the question. I think it will end up being the 2.8 version, with tape around the white bits.
