And it is quite a surprise:
Popular online retailer Amazon Italy may have just leaked the fourth playable character in Donkey Kong Country: Tropical Freeze. The box-art for the Wii U exclusive now features the long-standing Cranky Kong. Hopefully we will see some new footage of the game at this year’s VGX awards, which Nintendo of America president Reggie Fils-Aime should be attending.
