It has been confirmed that SEGA will have Yakuza 4 playable at E3 this year. If I’m correct, this is the first Yakuza game to appear at E3 outside the first one. Correct me if I’m wrong.
Regardless, if you really want to get some hands on time with Yakuza 4, you can always hit up the Japanese PSN and download the demo. Simple dimples.
