We have a US release date: Feb. 14th. I'm not sure about a Europe date yet.
Some info about special editions:
"We’re releasing Persona 5 in a special SteelBook® Launch Edition! All pre-orders and a very limited number of launch copies will come in an official, collectible SteelBook case, adorned with glorious Persona 5 art (identical to the one in the “Take Your Heart” Premium Edition). It’ll be $59.99 at launch! Exclusive to the PS4 version (it's also coming to PS3)."
There's a premium edition for $89. It comes with soundtrack, 64 page hardcover art book, school bag, steel book, and a 4" plush of the Persona 5 cat. The cat plush would be fun to have, and I bet that art book has some good stuff in it, I've never in my life bought a premium edition, and I doubt I'll start with a game series I've never played.
I like the Steelbook on the regular/launch edition, though. Might put down a preorder for that.
