It seems that ZUN will release a new game at Comiket 78, titled "Touhou 12.8 - Fairy Wars". It is supposed to be a continuation of Strange and Bright Nature Deity.
Despite the lack of Touhou 13, this is pure awesome! The gameplay type seems interesting and unique. Not to mention - who would have expected Cirno to get a game only for herself?
I bow before you, ZUN-sama! ^^
