The manga releases have a consistent release date, one chapter at the beginning of each month, generally three volumes per year. It was the same with the novels at first with consistency before going kind of AWOL.

The only good news is the prequel novels were eventually released, and with the main manga steady it is largely certain that the next novel in this prequel, sequel series will be delivered… though ‘eventually’ is the best we can go on. Hopefully soon!
