Update: Nintendo has refuted the Amazon statement and has said, “the launch date of Mario Kart 8 has not changed.”
A number of gamers on the NeoGAF forums are reporting that Amazon has begun sending out emails stating that Mario Kart 8 is coming sometime before May 30th. The retailer says that we should expect the game between April 16 and April 19. This has led many to believe that Nintendo has pushed the game forward to sometime next month. Amazon support also sound confident of a new date.
