Damn, but it doesn't seem like he's going out on a high note in some ways, sadly. Ironically, what's still my favourite Tekken was one not directed by Harada (Tekken 2). It'll be interesting to see how the series goes forward after this...
@inochinagi some things to probably note is that he was planning to leave even before T8 was even a thing, so I don’t think Harada is leaving because of criticism with 8. Fast forward to T8's development, he finalized it saying he'll be leaving on Tekken 9 as his last game.
Fast forward again and now he's leaving by the end of 2025. That's quite the dramatic shift of time placement in leaving.
