Katsuhiro Harada is in between a rock in a hard place. In an interview with Gamespot, the game director responded that Street Fighter x Tekken was "on hold" for the moment to avoid "splitting communities". With fighting fans currently playing Street Fighter V and Tekken 7 rapidly approaching, it's not going to be easy to find "the right time" for both franchises.
Its not like anyone is actually expecting it anytime soon right? We've been waiting on this game since 2010? I'm sure we'll see it sometime close to never...quit yanking our chain Harada!
