Canon EF-M 32mm f/1.4

In all the buzz around the Canon EOS R full frame mirrorless, almost unnoticed, Canon announced the EF-M 32mm f/1.4 STM lens for the EOS M:

Aimed at entry- and enthusiast-level photographers, the EF-M 32mm F/1.4 STM is a small (1.99in/50.5mm long) and light (8.29oz/235g) lens that’s the 35mm-equivalent of a 51mm lens, which provides an angle-of-view that’s similar to the human eye.

It is the fastest lens for the system, an almost equivalent to the 50mm f/1.4 found on the EOS line. If I had an EOS-M, I’d probably get it to supplement the 22mm f/2 (pancake).

But will that system live in parallel from the EOS-R? For how long?
