Nintendo will soon release a new 'Midnight Purple' 3DS in America, major US retailer Sam's Club would have you believe.
The unannounced colour popped up on the retailer website, as spotted by a Joystiq reader, before being briskly removed again.Sadly, there was no picture or any indication of a release date, but it would appear an unlikely slip up if it were not related to some form of behind-the-scenes info.
If a purple 3DS sounds like your kind of style, hold off picking one up for a few weeks.
Nintendo recently released an important 3DS firmware update which adds folder functionality to the home screen, and support for game patches/updates.
