Ubisoft revealed this morning that the highly anticipated Rayman Legends will launch across the Wii U, Xbox 360 and PS3 on September 3 in North America. Until then, Wii U owners can get their hands on a new “demo.”

Nintendo announced that the Rayman Legends Challenges App is now available on the Wii U eShop. The “demo” challenges players to compete in online challenges across randomly generated levels. It’s a free download, and will remain on the Wii U eShop until the game’s full release in September.

The other major release this week is Mega Man 4 on the 3DS eShop virtual console. The fourth entry in the classic Mega Man series is generally considered the point where the series started to go downhill, but it’s still a solid game.

Here are the other releases coming to various Nintendo platforms this week:

The Nintendo Download is a little sparse this week, and probably will continue to be leading up to E3. Nintendo may not be hosting a large press conference, but we’ll hopefully hear news on what the company has planned for the eShop in the coming months.
