A Newegg listing stumbled upon by a NeoGaf user has Luigi’s Mansion: Dark Moon advertised as an upcoming Wii U game with no official release date. Could this listing possibly be a secret held by Nintendo about an eventual HD port of the popular 3DS game? Is Nintendo trying to add a much-needed first-party title to its holiday lineup, or is this just an error or typo made by Newegg’s IT department? It certainly is odd that the listing allows customers to pre-order the game, as if a release is imminent. If Luigi’s Mansion: Dark Moon launched on Wii U, would you purchase the game, even after owning it on 3DS? Let us know in the comments.
