Persona 5 is a major departure for the series regarding dungeon design, focusing more stealth and puzzle solving compared to the randomly generated dungeons from Persona 4. It makes for more dynamic and fun gameplay outside of the combat system. You can see this (in addition to hearing English Voice acting and some story bits) with the above trailer Atlus released.
While I’m personally tied of hearing about the game (just want to play it already; do not understand Japanese so importing wasn’t the best option in my case), I’m happy we are getting closer to it’s launch. It will see release on the PS4 and PS3 in April 2017.
