He doesn't have to be the lead writer, he confirmed he is supervising the game and was directly contributing on the new scenario's concept and tricks. The specific dialogue is not going to be written by him, but his characters are extremely tropey, same reason why they were able to have so many writers for THL without the characters feeling wrong in them.

Yes this, it was already directly confirmed he has a strong role in this department.

See, this is making assumptions. We know it starts on Jabberwock Island with the same cast. If this was V3 you could be complaining about a female MC or if this was THL you could be complaining the game looks short because there's only 100 days and a lack of choices. It is fully possible the twist turns this entirely on it's head fast and your assumption is completely wrong, all we know as fact is that the steam page confirms the length is equal to the original DR2, something they can't use a twist to fuck with.

We won't know what it truly is until it comes out but Kodaka has absolutely never been the type to settle or release something that doesn't drastically overshoot what he implied it was.
