PS4 is not selling so well in Japan, abroad from that country, PS4 is outselling One and Wii U. In Japan, the latest PlayStation system does not sell by inertia. Sony needs games to change that situation. Speaking about software, a big title could be announced at Tokyo Game Show.
Hirokazu Hamamura, former Editor in Chief at Famitsu, claimed the following during a Youtube event:
“I heard the leading manufacturer and there (of PS4 title) is a big announcement from TGS”
Supposedly, Hirokazu was referring a game from a third party developer. Therefore, what game could be? Forums are burning in suppositions: Resident Evil 7, Dragon Quest, etc.
