* DevelopmentHell: The remake was announced in 2008. Four years later and all we know is that it ''is'' being worked on and will be the next project after ''[[FateExtra Fate/EXTRA CCC]]''
** There's some [[http://www.siliconera.com/2012/12/14/tsukihime-remake-artwork-shows-off-new-character-designs/ concept art]]...
* HeyItsThatVoice: Shiki has both of [[Manga/{{X1999}} Kamui's]] voice actors: Creator/KenichiSuzumura ''and'' Creator/SteveStaley.
* TheOtherDarrin: The anime's voice cast is entirely replaced by that of ''MeltyBlood'' for succeeding appearances.
* ShrugOfGod: Supposedly, a request to describe Altrouge's appearance was declined because "it's more interesting that way!"
* {{Vaporware}}: Tsukihime 2: The Dark Six. It got a NoFourthWall trailer in Kagetsu Tohya and three prologue chapters have floated around the internet forever. Not a single other thing is known about it, never mind a release date. The Tsukihime remake used to be this, but it was finally officially announced at the end of the Tsukihime manga.
* WhatCouldHaveBeen: Satsuki was originally supposed to be one of the main Tsukihime heroines with her own route. This was removed at the last minute and she simply became a minor character. The upcoming remake is supposed to finally include a route for her.
