"Tekken" series producer Katsuhiro Harada teased an announcement on his Twitter feed on September 17, 2010 ("TGS Sep 18(Sat) at Tougeki Booth. I'll announce something :D"). It was rumored to be something related to "Tekken X Street Fighter" or "Tekken 7". The game was announced to be "Tekken Tag Tournament 2", sequel to "Tekken Tag Tournament", on September 18, 2010, at the Tougeki event as promised. Producer Katsuhiro Harada stated that the game engine would be different from the one used in "Tekken 6". The release of the arcade version of the game in Japan was originally planned for summer 2011, but due to complications derived from the Great East Japan earthquake, the arcade release was postponed until Autumn 2011. At the World Cyber Games 2010, Harada stated that the console version would feature additional console-exclusive returning characters and bonus gameplay modes. He also suggested that the release of the console version of the game would take place between the releases of "Street Fighter X Tekken" and "Tekken X Street Fighter".
