What are the chances?

I still love my M6II. I would certainly consider an R mount version of it, especially if some more of the excellent EF-M lenses get ported over to RF mount. I kind of agree with you about the R50, but definitely not the R8. Just because it has pretty much the same body as the RP, it doesn't follow that it's just a stale refresh. It's quite clearly the best full frame camera in its price range, by a long way. To get the same sensor and AF system, and e-shutter burst rate as the R6II for $1000 less is the complete opposite of crippling. To read some people on these forums, you'd think they expect Canon to give them everything from a more expensive camera, but for a lot less money. To lose only IBIS, a second card slot, a higher capacity battery, full mechanical shutter (which I have never used in over two years on my R and eight months on my R7), and the 12fps in EFCS for a saving of $1000, and plenty of weight and size too, is quite an amazing deal. I'm torn over whether I want to replace my R (eventually) with the R6II or the R8. My R7 is the first camera I've had with IBIS, and it is nice to have it. On the other hand, most of my lenses have IS, and the main one that doesn't (RF 50 F1.8) is used mostly for people shooting, where I need to keep the shutter speed up anyway. Of the differences between the R8 and the R6II, the lack of IBIS is the one that gives me most pause. But I've been very happily shooting my R for well over two years without IBIS. Probably by the time I come to a decision, there'll be yet another camera to throw in the mix.
