It's up for pre-order on all the digital stores.
There's a deluxe edition:
"The Jurassic World Evolution Deluxe Edition includes a pack of 5 extra dinosaurs that can be accessed through dig sites within the game.
and two skins as a pre-order bonus:
"Pre order and receive an exclusive skin for the ACU helicopter and the Ranger vehicle."
(Edit: they're different colours for each platform; green for Xbox, blue for PS4, orange for Steam - https://www.jurassicworldevolution.com/pre-order )
I think this is probably the final box art, it's unfortunately very uninspired:
