During the special premiere event for 3D movie of Kara no Kyoukai: Fukan Fuukei (空の境界: 俯瞰風景), a new Anime adaptation of Fate/stay night was announced and will be produced by ufotable, the same producer of another TV Anime Fate/Zero. The announcement was also confirmed by Hikaru Kondo, the CEO of ufotable.
Fans could recklessly infer that the new Anime should more or less be another movie (or less likely, a new TV Anime) following Sakura’s route, i.e., Heaven’s Feel due to the fact the other two routes were already covered in TV Anime and UBW movie. So far no other information is available and we will get back to this soon. Check out the PV of the ufotable quality.
