Both Paper Mario: Sticker Star and Luigi’s Mansion: Dark Moon have been given dates. Paper Mario will be arriving on Sunday, November 11, 2012, while Luigi’s Mansion has been delayed to “the first half of 2013.”
It’s interesting to see two Mario games releasing so close to one another. Paper Mario in November, and New Super Mario Bros. U expected sometime this holiday season. Also, please keep in mind these are dates for North America.
