Maybe Shamoke will finally be playable in Dynasty Warriors 9.
No way they're showing Ninja Gaiden 4. It's way too soon. Nioh is their big action game title at the moment. We will probably see Dead or Alive 6 announced first. I don't expect NG4 until like, 2019.
I agree, but the way Koei Tecmo and their teams are pretty darn efficient these last few years, I'd venture to say Q4 2018 for Ninja Ryu's proud return (to form, hopefully).
Especially if DMC5 happens anytime soon within the next few years, no way is KT going to sit idly by and allow THEIR stylish action hero to continue to be benched.
EDIT:
Honestly, KT is the best Japanese publisher this gen. Lots of games, lots of new IP, more Japanese publisher need to learn from them.
The thing I love most about KT is that they started righting their ship pretty early, last gen. Following the merger, they started being much more efficient as a dev, and never fell into some of the failings that other JP publishers did during that era.
To be able to come out of the PS3/360 era alive and well, while only have a few honest missteps to the tune of "DW6", SW3 Wii exclusive" and "Ninja Gaiden 3" to their name? I'd say they made out pretty well. And this gen has been even better for them.
