National Convention 2016 is the way they named the tournament that took place this week. Since it’s also the 25th Anniversary of World Warrior they included an SF2 tournament with players from SF4 like Momochi, Itabashi and Bonchan also including 2 of the 5 fighting gods, Tokido and Haitani.
Three ST players were also invited, Yaya, Komoda and Gian. The commentator was Yoshio (aka the Japanese James Chen). They used a PS3 port of the game. Single elimination, single game (!)
