It will be airing on dTV (like Kisumai Dokidokin) starting October 16.

The trailer is up on Youtube and ... wow. They are writing fanfiction for their fans *lol*

I checked the dTV site. You can register with a normal credit card (e.g. VISA), but the fine print says that videos are not shown "overseas". I assume that means international fans can't watch it.
I hope they release a DVD.
PS: for those of you interested - Busaiku's stageplay will be available on DVD later this year. It was announced on Johnny's web (https://www.johnnys-net.jp/page?id=discoDetail&artist=17&data=2366)
