well i know that, i use ltsb/ltsc since day 1! for now everything runs fine and if you are on 1511 or 1607 and buy something new which is not supported, you can still go to 1809. so everything will run fine for now. i will never use anything else then ltsc. i rather wait with buying a new graphic card then, if it shouldn't be supported by 1809 in the future, until there is a new ltsc version. i know ms said the next ltsc release will be next year and that would be fine with me, but somehow i got the feeling we get it this year already, just like with 1511>1607, it came early too. depends when the update with new startmenu and livetiles will be release for normal editions, if they manage to release it this october, i bet there will be a new ltsc release at the same time. not because they want to push that feature to ltsc, but because it will be easier for them to maintenance all the different versions.
