This morning, we got a rather good look at Rayman Legends thanks to a leaked video. Surprisingly, Ubisoft has since commented on the situation with about as candid a response as one could hope for. Here's the statement that was provided to Eurogamer:
Excellent to hear. I'm eager to see how the final version of Legends will compare to what's been shown already; it's not every day we get to see games in this state, but it's always fun to look back in retrospect. More than anything, though, I'm happy Ubisoft is continuing to put out Rayman games.
