then yes, ZUN made a announcement stating the following
1) ZUN said ULiL PS4 has plenty of work that only he can do, and it is a special game in every sense of the word. Well, that's not exactly saying much.
2) The language he used about voice acting was so severe it's funny. "Adding voices would be a huge disappointment. I'll do my best to prevent it." Makes me wonder whether he thinks the players have a strong demand for voice acting, or if Sony has been pressing them for that.
3) On new character(s): ZUN said you can't just add random characters to the game. He might add someone who makes people suspect "something has begun."
4) There will be more info on ULiL PS4 at Reitaisai. Also probably at Reitaisai: flyers for Vol. 2 of Strangers from Outer World.
5) On manga (hope you've been keeping up): ZUN said the February chapter of Forbidden Scrollery is interesting, and the following March and April chapters of FS, and the next WaHH will all be interesting. We will see some changes in FS's story. He sounded unconfident. Okonogi: "You feeling nervous?" ZUN: "Quite."
6) Okonogi also had an announcement to make: ZUN will have plenty of things to write this year, and by things to write, he didn't mean more CoLA. Considering it's unlikely for ZUN to start a fifth serialization, and it doesn't seem the right time for a third Akyuu's book, this new thing sounds like another book on Gensokyo that's not written by Akyuu. In fact, after Okonogi said that, Unabara reasoned that it might be a new Grimoire of Marisa, a thought no doubt shared by many fans.
