Looks like Canon will soon announce new lenses for the RF mount. One of them might come with the form factor of a pancake lens.
The Canon RF 16mm f/2.8 lens is also a non-L prime lens which has not appeared on the roadmap until now. This lens is probably for a full-frame sensor, but it may also be a very useful wide-angle lens for APS-C cameras. The RF 16mm f/2.8 might be a pancake lens.
