As predicted yesterday following a Tweeted tease from Yakuza creator Toshihiro Nagoshi, Yakuza 5 has been confirmed to be in development.
The confirmation comes from the pages of Famitsu rather than Nagoshi himself, and also brings with it news of a sequel to PSP series spin-off Yakuza Black Panther.
Famitsu says (via Andriasang) the new portable title will be called Kurohyou 2 Ryu ga Gotoku. The Black Panther follow-up apparently retains the basic gameplay mechanics of its predecessor and will be playable at this year's TGS with a release set for spring 2012.
We're expecting more details to be revealed about both games at a Sega press conference later today.
