I've been thinking that as well. It could be that Ishibumi was looking for a new production company, and that being the reason for the delay. Even so, from what people have told me they've said that the Anime 'is in the works' I haven't seen any evidence of that yet. I assume IF it is a new production company, then they're going to wait until they start working on production before making an announcement.

+ Does anyone know if TNK have finished the production they're currently working on?

Just by looking at it, there's no release date for either Summer on winter 2017 yet; which to me makes me think it's not even finished yet.

It's probably going to be a few more weeks or so before we start getting info. I guess Ishibumi just wanted to give fans reassurance that there will be a new season or movie...whatever.
