Just sounds like typical PR to me.
No company is gonna come out and say "It's even more dense and esoteric than the last game!
While I get and I agree with what you say, if by 'last game' you mean P4 then that was not dense or esoteric. I mean there's a reason why is called by some as "Scooby-Doo: The RPG".
Atlus would be crazy to not cater to the immense popularity P4 produced.
Well... the thing with this is that Atlus (for years now) took that popularity and did manga, a novel, an anime series, live concerts, albums, a port for PS Vita, two fighting games, two spin-offs, almost all kinds of merchandising and most likely more stuff I'm forgetting.
So Atlus already
catered to that demographic with P4 enough to get sick of it if they wanted.
