I wonder if an Apo-Lanthar level 10mm, 15mm or 18mm could be possible. These would clearly be lenses which I would be interested in.
Apo-Lanthars in the range 75mm, 90mm or 135mm would also be killers.
And please in e-mount in addition to other mounts!
I think it is possible, but perhaps not very practical or desirable because of price and size. Ultra-wide APO lenses do exist in theory, but manufacturers probably assume most customers would not be willing to pay the price or carry such large lenses.
That is likely why we see ultra-wides with slower apertures, like f/3.5 or smaller. Slower apertures help minimize CA and also allow the design to be more compact and cost effective.

Apo Lanthars do not need to have an f2 aperture. For ultrawide (10, 15, 18mm) as well as tele lenses (75, 90, 135, 180) f3.5 or f5.6 would be fine, just that they reach the PERFORMANCE of the Apo-Lanthars.
The f3.5/50 Apo Lanthar available for m-mount is one example of an excellent and light weight slow Apo Lanthar. It is more about the effort they put into color correcting that designates an Apo Lanthar, at least that is how I interpret their use of the label to date.

I'd love a 85mm f/1.0 from Voigtlander for sure
Voigtlander doesn’t do 85 just 90mm 😉
And I doubt they’ll ever make such a fast one.
It would need a 90mm front element and would be massive, heavy, just not great to use with manual focus. You can look at Sigmas 135mm f1.4 to get an idea of how big it would be. It would just be a little shorter because of the shorter focal length, but just as chunky otherwise.
I'm just going to say what I always say. They should start making film cameras again. Suddenly the Bessa's look cheap, and the Bessa III specifically is one of the finest medium format cameras made from a usability perspective. Put them back into production, make parts, film is not just coming back, it's fully back.
How about a Voigtländer 135mm APO? There are very few real options at 135mm for the M-mount. Leica has made some excellent lenses over the years, like the 135mm f/4.5 Hektor, the 135mm f/2.8 Elmarit, the 135mm f/4 Tele-Elmar, which I still think is the best of the classic designs, and the most recent 135mm f/3.4 APO-Telyt, which was discontinued in 2018.
As it stands today, there are essentially no current 135mm lenses available for the M-mount. That leaves a pretty obvious hole in the system. This feels like a missed opportunity for Cosina. Historically, 135mm was never a focal length they seemed interested in, and it has never been especially popular for rangefinder shooting, even though modern M bodies do include 135mm framelines.
Considering Cosina is already producing lenses for Sony, Canon, and Nikon mounts, making a modern, high performing 135mm for the M-mount, and possibly other mounts, would make a lot of sense. It would finally fill a gap that has been ignored for far too long...
I would like a small 28mm f2 Ultron for E mount. The f1.5 Nokton and f2 APO are just too big. The Ultron is perfect for me on the M. So small, so svelte.

The paid speed pass only gets you a 2 hour advantage, so it's largely for press to do interviews before primary crowds.
I will be attending this year since all my favorite booths will be there!
Of their 32 M-mount lenses, 29 are 50mm or wider, so they are well-covered.
The 75/1.5 probably outsells the two 90mm lenses (at f2 and f2.8) by a lot. To interest the public imagination, lenses need to be special, to have that certain something.
Right or wrong, I have the sense they are making longer lenses for more general use, in the two 90mm options. I'd like to see them try a 100/1.5, since the Otus Sonnar 100/1.4 rolled out of their factory 6-7 years back. They have the tech and know how and glass for this to happen.
The current 90/2 is an 8/7 and the 90/2.8 a 7/7 design, these are cramped designs that for their main correction lean heavily and exclusively on APD glass. Cosina has to accept and anticipate EVF ability (be it Viso or EVn series bodies) in Leica's near future, and to build up their portrait lens inventory.
So I want to see a bolder agenda, worrying less about the last half percent of CA, and more on greater bias towards portrait-friendly lower contrast telephotos, more organic correction via high refractive index glass and use an asph at the rear, like Otus v1 lenses do, their 75/1.5 too. 11/8 for a 100/1.5 would do the trick - and up the blade count from 10/12 to 14-15-16.

I also got registered already and didn't consider the paid pass (new from this year) to be very useful. I will probably take Friday (2nd day of event) off from work and go then as it's usually more crowded on the weekends and 1st day is partly reserved for VIPs and paid pass participants. I may go 2nd time during the weekend if it feels like there's still more to see and do after initial visit.

It will be very much time that Canon stops being a bitch and allow Voigtlander to port the existing 50 APO, 65 APO, 110 APO and 21 Nokton to RF mount.
The willingness to accommodate other makers of lenses is one of the biggest strengths of the Sony system. It really differentiates this company from many others whose restrictive mindset was ingrained in analog times.
(Unfortunately Canon isn‘t the only one, that needs to be called out on this issue).
