Way back in 2008, Tech Gian announced plans for a remake of Fate/stay night creators TYPE-MOON's vampire visual novel Tsukihime with new, enhanced artwork and sound, changes to the storyline, and the originally discarded route for Yumizuka Satsuki. Last year, TYPE-MOON Ace 10 said that the action is being moved closer to Tokyo and previewed new characters. An early look at TYPE-MOON Ace 11, out April 15th, says, well, more event CG has been previewed.
Reportedly release details are still to be announced. Beyond saying that the game is currently in development, indications are that there's no news in the feature.
