Canonrumors has an "all but confirmed by multiple sources" story that Canon will have 100MP+ full frame sensor camera in early 2023. That seems excessive to me, but maybe there's a newer CF Express format on the way that can deal with whatever absurd burst rate that thing will support. It's also supposed to have a bunch of relatively inexpensive RF-S lenses coming real soon now. The RF mount doesn't have many inexpensive lenses as it is, so any move in that direction will probably be seen as a positive step.
It only took me a little over a day to sell my RP, an EF lens adapter, a few EF lenses (35mm/2, 50mm/1.8, 85/1.8, 18-135mm/4-7 EF-S) and my gimbal. I might be short a camera body this summer, but that will cover what the R7 costs. The 85/1.8 hurts a little bit, but I like and use a 135mm/2 a lot more. The rest of those lenses really haven't been used in years.
