Right before the grand finals for Ultra Street Fighter 4 at the EVO 2014, Tekken director Katsuhiro Harada officially announced the development of Tekken 7. During the announcement, he claimed that it actually wasn’t the title he had meant to announce that day and only did so because of the leaked news from AOL that same day. He also mentioned, before showing off a teaser trailer that featured Heihachi and Kazuya’s mother sans any gameplay, that he is working on two other unannounced titles. One of these will be announced this year at San Diego Comic Con alongside more information for Tekken 7.
