One of the more exciting and prolific developers, Sega, has recently opened a new site for the upcoming Tokyo Game Show. The site features content based on the games that will be making appearance at TGS, however this list is by means final and knowing Sega, more games will be added to the roster as TGS draws closer.
So far on the list we have Yakuza 1&2 HD Edition (PS3), Yakuza 5 (PS3) as well as Phantasy Star Online 2 (PSV, iOS, Android, PC). These are first party titles, for their partner companies there will be Medal of Honor War Fighter (PS3, X360, PC), Need for Speed Most Wanted (PS3, X360, PSV, PC) and FIFA 13 (PS3, X360, PSV, PSP).
Sega will also have a couple of booths dedicated to selling game related gear and also for stage events.
