An eight to ten year gap between mainline games in the Shin Megami Tensei family (Persona included) is not unusual. Persona 4 was a PlayStation 2 title released in 2008, basically two years into the life of the PlayStation 3. This odd release decision didn't stop P4 from successfully continuing the Persona legacy of being a cult RPG favorite in the west, that the series had really maintained since 3. Persona 5 was almost released in the same way: It was announced for release on the PlayStation 3 in 2014 (the same year that the PlayStation 4 launched in Japan), but the following year saw the platform changed to both PlayStation 3 and PlayStation 4. We'll never know how things would have gone for P5 if it had remained only on the PS3, in an era where it's becoming an increasingly ridiculous idea for your average gamer to keep anything older than the current generation of console hardware hooked to their TV.
