The first trailer for the PS4 and Vita version of Iwahime: Matsuri has been released. The visual novel which was originally released for the PC comes from Higurashi (When They Cry) creator, Ryukishi07. Not much has been said about differences in content between the PC version and the ports, but it seems that the PS4 and Vita version of the game will apparently have a new prologue.
Iwaihime: Matsuri is set to be released on the PlayStation 4 and PlayStation Vita on July 20 in Japan. There is currently no mention of a Western release.
