It was supposed to cross the universes of Namco's Tekken and Capcom's Street Fighter into one game, creating a roster from both franchises.

[5] Katsuhiro Harada did reveal some concepts at Gamescom 2010 such as a prototype model of Ryu, with the gi of Tekken's Paul Phoenix.

[7][8][9] In March 2012, Tekken producer Katsuhiro Harada clarified that the poll would not decide the final roster, but will instead be used in conjunction with various research methods to determine the character lineup.

[11] At the 2014 San Diego Comic-Con, Harada confirmed that the game was still in development, with the reason for the scarce information being due to Bandai Namco waiting for the opportunity to market it.

[13] In December of the same year, Street Fighter's Akuma was announced as a playable guest character in Tekken 7: Fated Retribution, though no statement was made as to whether this was an indicator of the crossover title's status.

[20] The game was referenced during EVO 2023, where Yoshinori Ono, who had now parted ways with Capcom, made a surprise appearance on stage with Harada, claiming that they had left some "homework" behind.
