Nintendo has provided release dates for New Super Mario Bros. U's Luigi-themed update. You'll be able to get your hands on the content either June or August, depending on whether you decide to download the software update or wait for a retail release.

The New Super Mario Bros. U DLC is coming June 20, and it will cost $19.99. The standalone release of Super Luigi U follows a few months later on August 25. That one will set you back $29.99. 

In addition to tailoring levels toward Mario's little brother, the DLC lets players choose to play as Nabbit, the thieving rabbit from the game's vanilla release. Nintendo says he's designed for novices, because he doesn't take damage from the bad guys. It looks like Luigi is managing to get upstaged in his own game.
