Look forward to your impressions of the 5D4.

I checked this morning and my shutter count is right around 50k. Might need to take up time lapse photography so I can justify a new toy.

Until then I've decided to go through the owners manual, learn and try things that I haven't and keep my money in the bank. My "issues" with the 5D3 really do not amount to much. As you say, the output is great.
