I don't think it's accurate to say KT is full on board when their only upcoming release of note(Dynasty Warriors) is skipping the platform and the other sub-brands will follow that lead. Nevermind their other big brands.
I thought this was interesting. So I kind of broke down what KT does. Yeah, a mainline Dynasty Warriors looks unlikely. I also think these titles would be unlikely/impossible:
Dead or Alive (Likely won't come to Switch)
Nioh (If they make another one, it probably will be PS4 console exclusive)
These are the series likely or already on the Switch
Winning Post (Has Switch version)
Nobunaga's Ambition (Has Switch version)
Romance of the Three Kingdoms (Has Switch version)
Fatal Frame series (Would likely be Switch if they make another one)
Nights of Azure (Coming to Switch)
To break it up by Divisions:
Tecmo This is probably the division that would be most adverse to making Switch games. They try to push the tech and have an outlook toward the West.
Koei They port their sim games to everything. Even the Wii U. Switch will continue to get them. They will probably continue to not sell that well, but that doesn't seem to matter.
Omega Force. Switch will get FE, One Piece and maybe another Zelda but not main series or Toukiden (they could put one on the Switch, the engine works on the PS3, but they probably won't bother).
Ruby Party Stuff is almost exclusively mobile or handheld (3DS and Vita). The last console title they released was for the PS2. They are not going to move to the PS4 exclusively. They will put something out on the Switch or Switch/PS4 or they will go full mobile (that might be the likely one).
GUST I suppose it depends how Nights of Azure does. But I still don't see them surviving in a PS4 only ecosystem when the Vita is no longer viable. At this time they don't produce the type of titles that wouldn't be possible on the Switch, it matters more if they feel it is worth it.
Random:
Ninja Gaiden I kind of doubt any console will get new one for a while, but would likely skip the switch. Then again the DS got a Ninja Gaiden spinoff game so who knows anymore.
Deception I don't see a new installment this generation. But the engine they used supported both the Vita and PS3, so it would be possible.
Any games I am missing?
