Greg_E999 re: No date set but several sites are guessing October 2021 release...we say above that it will be the 2nd half of this calendar year. Correct, that we have not published a release date. But it will be the same day that Windows 10, version 21H2 is released.
We haven't made any changes to how you get LTSC versions - if you are licensed for Enterprise, you can get it from the Volume Licensing Servicing Center (VLSC). The next LTSC is for certain going to be Windows 10, so not sure what you are asking with the Windows 11 part of your comment. If you want Windows 11, that will be released on Oct. 5, 2021, and will be available to be deployed via all normal channels: WSUS, ConfigMgr, Windows Update for Business, MDT, etc... view our Windows 11 docs here: Windows 11 overview - What's new in Windows | Microsoft Docs
