It never fails. Every time I post about crop RF somebody want to sell me the EF-M system.The EF-M 11-17 is an all around better lens than the EF-s 10-22 and it has IS and is also cheaper. The M line badly needs an equivalent to the EF-s 15-85 which is a very fine piece of glass, but the vast majority are happy with the 18-150, so it may be a while. Making an R body just for APS-c is silly. If you want the portability of your 10-22 and your 15-85, just slap them on your R5 and it will automatically switch to APS-c with proper APS-c RAW files and image quality and resolution better than your 7d II (yes, only 17MP, but the new AA filter makes a big difference).
But EF-M has never had anything that looked better for me, than what I already have. Neither when it comes to cameras (there's nothing like high-end enthusiast 7D series), nor when it comes to lenses. As for the mentioned lenses, a wideangle going down to 10mm (or lower) is very important for me. I think 75% of my photos shot with the 10-22mm are shot at 10mm. And similar for my standard-zoom, a very high rate of my photos are shot at 15mm. So practical to have 15mm in my standard-lens, so I never gonna have another "kit-lens" that doesn't go down to the 15mm (equal to 24mm fullframe).
Also I will never buy a $4000 camera (R5). And definitely not a $4000 fullframe camera only to use it in 17MP crop-mode with a max burst rate at 6 fps when shooting full bit depth RAWs with mechanical shutter.
But most importantly, when I choose a mirrorless system I want to choose a system (with high-end cameras and lenses) I see live and grow big in the next 25-30 years to come.
