They probably figured on a small uptake, very few even know of its existence. I'm happy they are taking their time, it is an important lens for them.
Lost in Japan, this site will include the 15mm when they get to it, but here is a interesting comparo (usual caveats apply) between the 17mm TS and 21mm Zeiss, the 15mm will be similar, going on its MTF:

i was very excited to pick up my 15mm F2.8 ZE today but of course (to my great annoyance) zeiss haven't released the 95mm UV filter simultaneously with the lens so i'm stuck with a rather exotic paperweight until the filter arrives.

?? Are you exclusively shooting above 5 kilometers in mountains ??
I have purchased one UV-filter, it was to my first SLR-lens I purchased new in 2002/2003 (Sigma 24-70/2.8EX). I think I used it once... but we don't have mountains here...

no, i have always used a UV filter as protection on my zeiss lenses.
i have followed all the arguments pro and con using a filter and the one time i didn't use one (on my 30 year old zeiss 25mm F2.8 AE) i managed to get a small spot of residue on the front element. i opened up my new zeiss lens cleaning kit and VERY carefully wiped the spot off promptly leaving a nice scratch in the coating.
never ever again.
zeiss are quite clear that a good quality filter has no visible impact on the MTF of a lens and if it is good enough for them it is good enough for me.

OK I see your point from your personal point of view. I have been lucky and have had no major issues with lens cleaning - thou I'm not collecting these lenses and I just don't care if there would be few scratches on my lenses since they anyway won't have any effect how lens behaves optically.
For me biggest issue for using filters is that the already too small hoods of ZE/ZF lenses, are even "smaller" if one is using filter, which is 5-10mm further away in front compared to front lens surface. Also when sun (or other light source) is shining to lens it gets always much worse if I have filter in between. Thou I don't have experience of Zeiss UV-filters since I only use high quality polarizers. The few high quality UVs I have tested (Leica and B&W which came with some lenses I had purchased) cause catastrophic contrast lost, and cheaper stuff like Hoya HMC Pro1 is just ridiculous in backlight.
What comes to sharpness, resolution or even colors I'm sure Zeiss UV-filter doesn't have any effect when shoot in front light. But it's pretty bold claim from Zeiss to claim that good quality filter has no visible impact, they must be only shooting in easy conditions (front light, no reflections or light sources shining towards lens) or they are just blind.

It's possible older coating technology was less durable than that currently available. You'll see that lots of vintage lenses for sale on various boards frequently mention cleaning marks and/or small scratches. That said, I have some small coating marks on a few of my Zeiss ZM lenses after only a year or so of ownership. I definitely haven't babied them, but also haven't intentionally abused them. Naturally, for there to be coating marks, I haven't used filters on them for protection either.

I am cleaning lenses for 20 years (mostly Canon) and never had any such mishaps. Are Zeiss lenses more sensitive in that regard? If so, why?
My experience of T*-coating (Contax and current Zeiss ZE/ZF, don't have experience of others) is opposite; it's very resistant to scratches etc.
I'm usually carrying two cameras (one each shoulder, or one on shoulder and other on tripod), and the dense forests I'm shooting I'm constantly walking between trees/bushes etc. and between shots or after getting back home I'm wiping everything from spider webs, pollen, dust all the way to hardened/dried spruce resin off from front lenses. Naturally I have hoods in all ZE/ZF lenses all time, but I rarely anymore use lens caps. Also I'm shooting in rain quite often, and the raincover covers just the "cylinder" part of the lens, front lens is exposed to rain, naturally hoods will prevent rain going to front lens element.
Also in order to some scratch have effect to image it needs to cover really large area of the front lens, and I shoot in backlight all the time and have to remove pollen from lens sometimes since it seems to lower contrast (pollen is bright yellow, while scratches could be painted black). Only some of my older Pentax and Nikon lenses from 1970s have coating defects, which can be seen in final images. From my viewpoint I see people babying their lenses way too much. I understand it if one is planning to "rotate" lenses all the time and has to worry about resale value. I'm going to shoot with my Zeiss ZE lenses for a long time, at least 15-20 years or as long as they last (or camera system available).
....there is a drop down for each lens to change the aperture......
but the link itself is to the aperture I specified. Some people may not notice that.
If you want we can change (you the filter and I the lens
