I highly doubt it. A classical double-Gauss design isn’t really sufficient for f/1.2 in the modern era. On mirrorless, to get 45–50 mm you usually need the optical center farther from the image plane, which already complicates things. So why stick with a simple double-Gauss when you can move closer to the image plane and gain sharpness essentially for free? On top of that, an f/1.2 design clearly needs more glass elements in general to handle aberrations. Just look at Nikon’s 50 mm f/1.4 as an example:

Not happening. That would cannibalize the RF 50 mm f/1.2L like crazy. And they also want to sell mark 2 at some point. Sigma 40 1.4 is a beast of a lens. Plus, the “STM” label usually means fewer and lighter glass groups to move, not the kind of complex optical design needed to match the Bigma.
Exactly — the whole idea feels very Nikon-inspired.
I doubt it. A 35 mm f/1.2 would definitely be
the halo lens, but Canon would never slip it in as a typo. That would be an L-series with USM/VCM, not some mysterious “STM” entry.
I still don't buy an idea of STM Cine lens.
