What's funny is that Capcom RETROACTIVELY brought in Japanese VA to give DMC4 a Japanese audio track for the special edition. DMC games never had Japanese audio before but for the SE they have a Japanese track
(meaning you can finally hear Vergil and co in Japanese to fulfill your weeaboo dreams).
That's one of the big evidence going towards a DMC5 in the works because it makes little sense to add a complete voice track to an 8 year old game. Not to mention bringing back the major cutscene director to make a few more cutscenes, which didn't make sense unless they plan to use him for DMC5 as well.
I just hope Capcom is going all in on DMC5 like they are doing with MHW. I don't know what the hell is going on with Marvel Infinite or the Capcom FG division in general.
