We know that Rayman Origins is going to be available at retail, but it looks like it might also be an eShop download. The title is slated for release on June 5th, but there's another line in Ubisoft's press release that points to a dual eShop/retail release.

"The full version of the game will be available at retailers and online on June 5, 2012."

Ubisoft and Nintendo work very closely with one another, so I wouldn't be surprised to see this happen. On top of that, the release date is the first 'real' day of E3. Seems like a smart move to make!
