On August 24th the Ryu Ga Gotoku live event was held allowing press and fans to come and listen to a talk about the new game and HD rereleases of Yakuza 1 & 2! 

4Gamer.net was there and has a few photos of the event.  

Apparently a preview trailer for Ryu Ga Gotoku 5 was shown at the event but everyone that was there is under embargo not to speak about it until it’s officially released. 🙁
