Steam makes it look like it is released already
I noticed this as well. Really odd, it doesn't have a release date on it but the page looks like any other for a game that is out and it's not listed under the "coming soon" tab, but in the "specials" tab. Odd. On top of that the digital premium edition is $44.99 right now, too.
Amazon has it for $47.99 and with your order you get the Ultimate Swordsman suit DLC.
Gamestop has it for $49.99 and you get the merchant pack as a bonus dlc which is the following:
- Unlocks a special character within each chapter of the game, offering for sale only items obtainable through side-quests.
- Valuable items, ingredients and schematics, randomly available in Merchant's offering
