The image, seen above, depicts what appears to be official signage. It clearly mentions the New 3DS model and says "Available 2.13." According to Kotaku, this is an official Gamestop promotional poster, though Nintendo has yet to officially confirm the image's claims.
The timing of the leak raises this rumor's prominence – Nintendo is scheduled to unveil a wide swath of information on its upcoming plans tomorrow morning during the first Nintendo Direct of 2015.
