During today's Nintendo Direct, Satoru Iwata confirmed that Rayman Legends will feature exclusive Mario and Luigi costumes for Rayman and Globox. This is basically Nintendo's answer to the platform specific costumes of Splinter Cell and Assassin's Creed (although the latter is still coming to the Wii U).
Rayman Legends is still thankfully on track for an August 30th release date in Europe, and September 3rd in North America.
Final reminder: It's the last day to get your free Wii U game with Mario Kart 8
