Sega has announced plans for another Sega niconico live broadcast set for January 25 (next Monday) at 8:55 P.M. Japan Standard Time. Scheduled for demoing are the Yakuza 6 demo and the Valkyria Chronicles Remaster for PS4.
Additionally, Yakuza Kiwami (which released today in Japan!) will be demoed, and some additional and as of yet unspecified new media/info for Shin Megami Tensei IV Final (which will release on February 10) will be discussed during this stream.
Personally I think it will be quite funny if Toshihiro Nagoshi shows up again, only to act stoic for 90% of the stream. It was strangely enjoyable the last time he did that.
Sign up for a niconico account and view the stream here when the time arrives!
