Twinfinite writes, "Specifically, the video is narrated by Kazumi, Heihachi's late wife and Kazuya's mother. This will mark the first physical appearance of Kazumi in the Tekken series, which is especially interesting considering how important she is, passing on the Devil Gene to Kazuya and subsequently to Jin Kazama, resulting in many of the recent games' events."
Hope it comes to PC as I don't have any current gen consoles.
Still pretty excited though.
