Starting with the 2020 TECH stream, we will reduce the number of TECH stream releases per year from three to two. There is no change to the LTS schedule.
Read our blog post about this change for more information and use this thread for any related questions you might have.
Thats great news (good enough to bring me out of hiding ;)). I think this is a move almost all users will get behind, and makes sense in terms of practicality.
So, the next LTS will be:
and then:
and so on?
I cannot judge if this makes sense or not, even after reading the blog.
I wonder if people could give reasons that would go against this decision (since your blog just lists the positive points). 
I think it might make more sense for Unity to drop the .4 or .3 on LTS version naming and just call them 2019 LTS, 2020 LTS and so on. No real need for the final minor version numbering in the case of an LTS version. Internally it could still keep that final minor number but what’s publicly displayed could be changed to 20XX LTS
In practice the 20XX.4 LTS has always been exactly the same as the 20XX.3 version. It just gets a number bump and the LTS label appended to the name. Other than that it’s just as if the 20XX.3 version kept getting bugfix releases for two years after the launch of the next major Unity version release.
But I agree it would simplify things a lot if the minor version number was dropped and it was just given the LTS label in its place.
I like the naming as it is now… 
So you want it to go from 2020.2 to 2020.4 LTS? 
The current naming convention will be 2020.3.xxf1 LTS.
Important is the LTS in the name, not the number. I know a project that has different numbers of step releases to the next LTS per cycle. Version numbers like 7.6, 8.7, 9.5, 10.4, but in communications only 7 LTS, 8 LTS…
It’s telling that literally nobody is against reducing the number of TECH releases. It’s a good call though.
Yes, It’s a good move.i’m glad unity did it
is there an official date for
next LTS 2019.4
Yes. When 2020.1 launches.
Around spring, so about 3-4 months from now I would assume
It’s Spring already… 
Yes, but Spring lasts three months. No one said it would arrive at the beginning of Spring.
I know… 
And actually Spring doesn’t start for almost another 2 weeks. 
The Spring equinox will occur on March 19th.
Unity 2019.3 was slated for Fall 2019 and got released in January. I wouldn’t wait for 2020.1.
I’m waiting for 2019.4.
