It will be released end of this month. Looks like an interesting ultra-fast lens, and also of a more modest weight than the alternatives from TT Artisan and Leica. A local retailer has it listed already, and seems it will cost 1750 euro.
The few things I could find about it look promising. And it could be a very useful lens for my pub&club-shooting.
Who else is interested?
Well, first, thanks for starting this discussion, as it reminded me that I had been wanting to try the CV 50mm f/1.1 version, but it had slipped my mind, due to various distractions. As for the f/1.0, well, yes, I will be paying attention, but will probably wait until I have seen user reports and images, rather than be an early adopter.
Any M-mount 50mm, that is a full stop faster than my Summilux-M 50 ASPH, is worth a long look.
I had noticed, in the ISO comparison of the M10-P, the M10 Monochrom, and the M Type 246 Monochrom, plus one of the SL-series cameras, posted at Red Dot Forum, that the 246 did quite well, when compared with the newer Monochrom, through much of the ISO range. So, as a user of the 246 Monochrom, who likes to shoot in the evening and at night, but also being a retiree, with my income significantly decreasing in a few months, as bi-weekly compensation for my unused leave time runs out, I am taking a look at decent faster lenses, as an alternative to acquiring an M10 Monochrom.
I plan to keep my Summilux-M 50mm ASPH forever, as it was my first love among Leica M lenses, the lens that lured me into adding the Leica M ssystem, in the first place, but there will be times when a 50mm f/1.0 lens would have a role to play.

By accident of availability, I learned to use Canon and Nikon DSLRs at the same time. I love specific lenses made by both Canon and Nikon, too much to quit either system. Since 2018, Leica-M has been my “mirror-less” system. I am, certainly, not an expert.
