Yesterday an Atlus teaser website updated its front page with three separate images of Persona 4's lonely bear, Teddie. Via Nico Nico, a video hosting service, Siliconera notes that Atlus plans to announce something Persona related on November 21.
Persona 4 originally launched late into the PlayStation 2 lifecycle, but Atlus later ported the JRPG to the PS Vita. Persona 4 Golden added new environments, animated scenes and brand new character data.
The livestream goes live from the Nico Nico website on November 21 at 8 pm in Japan, but the announcement won't come until 72 hours later. You know, when the fog lifts.
