Rayman Legends has now been officially targeted for release in 2013. Early on it was assumed as one of the November 30 release titles, but it kept showing up as a "launch window" title (stretches to March 31), and now Ubisoft have confirmed that it will release in 2013 to ensure the quality of the product.
While, Rayman Legends would have been nice at launch, it's also good that the console has some major titles lined up for release during the post-launch months when things usually dry up a bit. So perhaps it's not entirely bad news...
