Koei Tecmo Games changed the release date of the Attack on Titan Nintendo 3DS escape game the Shingeki no Kyojin Shichi Kara no Dasshutsu in Japan. The new release date is May 11, 2017 (the original was Marc 30) so you have to wait a little bit more than one month more for the game.
The price still the same. 5800 Yen + tax (package / download version) and 12 800 Yen + tax (Limited Edition). You can get the download version with 10% OFF in the first two weeks.
