Visually it looks weak, although of course it is not the strong point of this studio, as I understand it Platinum from a full-fledged studio has now turned into a traitor who will help other studios finish their games for cheap (Sad...)? I will wait for trailers and announcements closer to the release while the mood is extremely neutral, especially after the 3rd part.
Well, they are not suicides, this series of games has never been distinguished by big sales, after all, everyone wants to make money. My guess, Koei does not really believe in the sales of the game, that is why she turned to another publisher, they themselves could easily publish it if they wanted, but apparently there are risks.
