I've been kinda worried about them too. Also because I felt their first releases were so strong and it's been pretty meh material since. It's a shame, because I really like their heavy sound and Sou's vocals are one of my favourites among current bands.
I think they don't have a label anymore, that explain why they aren't releasing anything. I won't be surprised if they annonce a disbandement soon (I hope they don't tho)
