As for NISJ development efforts, I've written a whole post earlier in this thread. I think it's too soon for Yomawari 3, but instead hope they port 1+2 to Switch first before releasing the third game for PC/PS4/NSW in 2019. Disgaea 6 seems like a given. Coven 2 would be cool too, but I expect that to stay in Japan (or NISA needs to announce localisation real soon). NISA have had since June 2016 to localise the game and add it to the PS4 version that was released in September 2017 in Japan. About the Penny-Punching Princess team, NIS will release a new brawler on March 8, 2018 in Japan for NSW/PS4/PSV, so there's that.
