Rayman Legends was on a crash course to release this month. Being that the game is completely finished, and was going to release early on the Wii U, a lot of people were very excited.
That is until it was postponed for really no reason at all. According to Ubisoft, they tend to release their games simultaneously across all platforms and didn't want Rayman Legends to be any different. I think Nintendo didn't pay them enough honestly.
Either way, even Rayman creator Michel Ancel and the staff from Ubisoft Montepellier are protesting the delay. Translated it reads "Release Rayman. Support Ubisoft Montpellier," with Rayman saying "Please."
