I believe next season is the last for the current alignments.

That is correct.
There could actually be a lot of movement if every team goes to the class they're supposed to play in..
Just out of that 5A district 8, if I'm not mistaken, Perry and Letcher could drop, and North could be moved to 6A.

And that's just one example. I'm sure that won't happen due to "geographical" reasons, but it could.
