This news comes from the newest issue of the Attack on Titan manga. It reveals that Koie Tecmo is working on a new Attack on Titan game for a PlayStation platform.
Not much else is revealed other than the sleeve saying Koei Tecmo x Attack on Titan and that the game will be out this Winter. It also doesn’t say which console the game will be coming out on. If you ask me though Koei Tecmo has said that they are not impressed with their Vita physical game sells and have since only brought physical editions of their games to PlayStation 4, so we could be seeing this on a current gen console .
