I would have to guess that it will be, along with the others. Arrange albums are very often included in anime adaptations.
Having never listened to Sasayaka na Hijimari in full until now (Ive been avoiding HF music), I can say almost for certain that this will be a very good choice as an ED. Just the sound of it works so well, you know, it has that ED feel, much more than the other Rewrite EDs. The lyrics as well.
In general, it has a very Bokura no Tabi feel to me, which is a very good thing in my eyes.
