I think it’s equally inevitable that there will within a year or two be at least two, possibly three APS-C RF models.
One will IMO be a very “affordable” entry model, complete with a new compact kit zoom, to entice newcomers to photography into adopting the RF system.
The other will probably be a 90D replacement. i.e. very well specified, but hi-end consumer rather than pro/semi-pro.
I’d like to think that there will also be a pro-grade sports/wildlife model that slots price-wise between the R6 and R5, to enable more “reach” with lighter and more compact lenses, as compared with FF.
