Now we see through a glass, darkly...

I am not one of them, but there are folks for whom the 7D line is the best camera choice there is, as best as I can tell. They know who they are. If they want something newer than the Mark II, they need to decide on their priorities and decide what compromises are worth it to get something else they want. For right now, it seems to me that the best solution for most of these folks is to use the 7D II until it breaks, and then buy another one (new, used, refurb). To get other features they want and to preserve the 7D II as long as possible, maybe a second camera with those features would be a good choice for their non-bird-or-sports-or-whatever shooting.
Most sports shooters use more than one body. I usually have a 70-200/2.8 on my 7D Mark II and a 5D Mark IV with a wider lens, either a 17-40/4, 24-70/2.8, or 24-105/4. At the wider fields of view, one can get by with slower shutter speeds. With FF cameras, one can also get by at higher ISOs if blowing out highlights (such as stadium lighting) is not a concern. My 7D Mark II shutter count is starting to climb into the "well past rated shutter life" zone, and I am beginning to keep my eyes open for low mileage used 7D Mark II bodies at significantly lower than new prices.
