Update: Bandai Namco has now officially revealed the various editions of the game, and they vary quite a lot between the US and Europe.
Europe’s editions are as described below, costing £84.99 for the Prince’s Edition and 139.99 for the King’s Edition.
In the US however, it’s a different story. A $74.99 Premium Edition will include the game, steelbook, 3D papercraft kit, music collection CD, an exclusive DLC sword, Dragon’s Tooth. That means no season pass.
For $199.99, the Collector’s Edition will get you all of that, plus an art book, a “Chibi Mechanical Rotating Diorama”, a Lofty plush, a making-of Blu-ray, a 3D papercraft display case, and the season pass.
