After the flop that was Street Fighter X Tekken , Namco Bandai has decided to let us know that Tekken X Street Fighter is still in development. According to director Katsuhiro Harada, the base gameplay system has already been finished. However, development of the title won’t continue until Tekken 7 has been completed.
Tekken X Street Fighter was first announced way back in 2010, and it’s likely that it will still be several years before it releases. That is a particularly long development time, and at this point it’s likely that Tekken X Street Fighter will come out on a console a generation removed from it’s predecessor.
