The 75/2.8 VM looks incredibly compact, and the 90/4 also very small - ideal for travel.
A range of aqua-phobic coated UV filter covering obscure sizes in silver and black; a good match for their portfolio.
The 35/1.4 Nokton in Z and RF; I'm not impressed with, as the focus throw is too compressed at regular taking distances to allow scale focusing; once a gain extending the helicoid to support very close focusing makes for a poor overall compromise.
APO binoculars is something new; however the chrome accents seem rather too attention grabbing.
Cosina also put up this CP+ 2026 page that has a collection of their latest product introduction videos and their new product catalog (also latest Zeiss catalogs for Cosina-made lenses):

I would really like the APO-LANTHAR 90mm F4 for e-mount!
As an interim:
Looking forward to Fred‘s tests, especially if the M-mount version works adapted to e-mount.
I think it might appear later as a mirrorless version since it's named APO-Lanthar ("a hallmark of ultimate performance") and there could be room for a mirrorless version since Cosina has nothing between the larger 75mm lenses and 110m for E-mount so far.
For me, the 40/2 Septon (E-mount) is the main lens from the new lineup that I'm interested in. I hope Cosina will complement it with a similarly sized 28/2.x pancake style lens (for FF mirrorless) in the future. Otus ML 35/1.4 is interesting but I can't justify the price (~340K yen for the pre-orders in Japan whereas 50/1.4 was 261K) to buy one for myself.
I will not buy the new VM tele lenses but I could consider mirrorless version(s) if they come out later. I think the 90/4 has a better chance of making it to FF mirrorless of the two.
I'll try to get hands-on time with the 40/2 Septon, 35/14 Otus ML and the 2 new VM lenses (can only try them adapted to my Sony A7CII) at CP+ this Friday and over the weekend if I go for a 2nd round.

Cosina announced Otus ML 35/1.4 today for April release (no specific date given yet). The official Japan price is same as for 85/1.4, so more expensive than 50/1.4.
This should be one of the new lenses that Cosina will show at CP+ this week. I believe they will also pre-announce their other new stuff that will be demonstrated there as prototypes later today (18:30 JST). Keeping an eye out for that.
It is almost the same size and the Otus 50 ML. The same diameter, less than a mm longer, and just 21 g heavier. The MTF charts look really good too with lower astigmatism than the Otus 50 ML. It also has 7 APD elements compared to 4 for the Otus 50 ML and 5 for the Otus 85 ML. All three lenses have 2 Asph elements.

It is just a guess, but I think Cosina is going to make a 75 f/2 APO Lanthar in the next year or so and that is the lens they will bring to FF mirrorless. Then the lineup at 75mm will be very similar to 28mm: a f/1.5 and f/2 APO Lanthar in Leica M and FF mirrorless and an f/2.8 that is only in Leica M mount.
My guess is that neither the 75 f/2.8 or the 90 f/4 will make it to FF mirrorless. They don't seem to bring slower lenses (except ultra wide angles) to FF mirrorless. They haven't even brought the 50 f/3.5 APO Lanthar to FF mirrorless and I think they would have if they were going to do so. To me the 90 f/4 APO Lanthar looks to be a similar lens to the 50 f/3.5 APO Lanthar, so I don't think we will see it in FF mirrors, but it is always hard to predict what Cosina will do.
My first thought was that the 90mm f/4 APO-Lanthar might be based on the older SL 90mm f3.5 APO-Lanthar, but this appears not to be the case. While they share the same .5m minimum focus distance the optical formulae seem quite different. The older lens has 6 elements in 5 groups, whereas the newer lens has 8 elements in 7 groups. The newer lens is also much lighter at 235g, versus approximately 387g (depending on the mount) for the older SL variant. The weight difference will be even larger when adapted to mirrorless cameras, since the M-mount adapters weigh less than any of the SLR adapters due to the shorter registration distance. Hopefully the optics have improved as well. Wide open, the SL 90mm is sharp in the center and corners, but there is a nasty mid-zone dip in resolution. With any luck the new design will mitigate this problem.
New binoculars and UV filters as well. I already have a Leica pair and the Zeiss Terra ED 10x25, so now I'm curious if the Cosina ones might actually be even better.
The CV 90/4 APO-Lanthar feels more in line with the CV 50/3.5 APO-Lanthar. It's slower and ultra compact, but optically superb.
Honestly, it will likely be the best 90mm M lens ever made in terms of resolution and contrast. Both lenses also share that tactile click beyond 0.7m. That detail was unique to the 50/3.5 APO before, and now Cosina has carried it over to the new 90/4 APO Lanthar as well...
The 90/4 APO is 104 grams lighter and 8.5mm shorter than the CV 90/2 APO-Ultron and focuses down to 0.5m (vs 0.9m)
It's cool they will now offer UV filers in 34mm for their lenses (silver and black)

A 410nm hard cut UV filter is a good filter to have for some Voigtlander lenses.
Interestingly, Zeiss UV filters also cut at 410nm.

The older 90mm f3.5 APO-Lanthar was just okay to me. It was decent for its time, but by today's standards of correction and resolution, it doesn't really stand out.

The 90mm f/4.0 Apo-Lanthar has a minimum focusing distance of just 0.5 m. That’s a very nice
It also has an indentation that signals when the RF decouples beyond 0.7m, which is very useful...a feature previously found only on the CV 50/3.5 APO-Lanthar.

If the 90/3.5 can match the 50/3.5 in terms of sharpness that would be great, but I hope that the 90 has smoother bokeh than the 50. I realize that bokeh is a matter of taste, but I prefer smoother, more modern bokeh than what the 50/3.5 produces. I would gladly give up a bit of sharpness for smoother bokeh. Not everyone will agree with me on that. :-)
