Well, you guys haven't disappointed me.
My two cents:
@Canon Rumors Guy has previously posted that an APS-C R body is coming from Canon. He's either right or wrong, but all the arguments one way or the other won't change anything.
Question is, if he is right, what form might that body take? I think logic would dictate a 7D or 90D successor. I don't see any point whatsoever in a low-cost crop sensor R. And by not seeing any point, I mean any point for Canon, which already offers the M line to fill that niche. Maybe if they completely abandoned the M line, but that would be a big leap off the cliff with no parachute.
The logic on this forum dictates that it would be a higher end crop body. I could see Canon offering a crop sensor R7 at about the price of the R6 or slightly above, which would be consistent with the historical placement of the 7D. That's going to disappoint the people who think they will get an R7 at 2014 prices. Don't see that happening.
We can (and apparently will) debate the viability of such a body until the cows come home. I can only relate my own perspective.
If Canon had offered a 7DIII with the 90D sensor, multiple f8 autofocus points and updated autofocus, I would have bought two (one for me and one for my wife). Instead I bought two R5s. I also bought her the 800 f11 and have two 100-500s on order (going on four months now) So, Canon not offering a 7DIII or R7 paid off for them in my case.
If the R7 ever materializes, I'm not sure what it would take for me to consider buying one. I'm perfectly happy with the R5 sensor and use it in crop mode consistently for songbirds with no problem. While I'm an extreme example, the point is that I suspect there are a lot of potential 7D III/R7 buyers who have moved on, meaning an even smaller niche for the body. A high megapixel R5s might shrink that potential market even more. if it means a crop mode of 25-35 mp.
Now, Canon's resources are not unlimited. They are having a hard time delivering on already introduced products, and I see a new post that says they are delaying future lens releases, so presumably, they are taking a close look at how best to allocate those resources once they meet current demand. We know the R3 is next in line. Beyond that, the more solid rumors are for a budget R, a high megapixel R, a cinema R and a flagship R (I may be missing other bodies). So, even at the most optimistic, it seems like an R7 would be unlikely to appear until 2023 at the earliest. That means it might be arriving about the time an R5II, which will likely have an even higher mp count, is being teased. Point being, with each new release, I suspect the pool of R7 users is going to shrink a bit.
Will it happen. I don't know, but I know it's damn fun reading all the arguments pro and con.
