Despite the well-documented financial issues of late, Atlus parent company Index Corp recently registered a domain for Persona 5 at persona5.jp. There have been rumblings of Persona 5 in the past, and it should really come as no surprise, but it's nice to see that things might be moving along.
The domain was registered on June 25, 2013, so it's still pretty fresh and no doubt warrants the hype of many Persona fans. Even if Index is just sitting on the name for the foreseeable future… PERSONA 5! Yeah!
