I can not see why Canon would not be quick to release RF versions of the most popular M series lenses as well as EF-S. In particular, I would not mind seeing the 35mm macro with built in light and the 10-18 restoring the coverage range lost unless you count the 0.71x adapters. Canon makes money selling lenses. Not having anything all those newly minted R7/10 owners find appealing would seem a mistake. Certainly RF 16 primes should be great for video but venues like RF Shooters will be deluged with questions like 'Can I use a FF RF on my RF-S?' by new folks who skipped reading the manual. It looks like they made a mistake releasing the R7 when they could not fill every order in a timely manner. A certain number of people have money and are planning a vacation soon. It would benefit Canon to send each of them off with an R7 and a couple lenses.
