I don't know.
All I can tell is the main story is already written (at least the Neus Route). lacks illustrations on the Epilogue, and then finish the unfinished parts and also the whole Blondie route.
Last year I thought I would finish it in a year, so if you ask me now, I would tell you the same as last year, and probably I will be wrong again.
But I doubt I will finish it soon.
