So in an interview that Kimishima did he mentioned that the NX is a home console. This is the first time Nintendo has referred to the NX as a home console so its official now.
"According to Kimishima, the new NX console will be a home console that is sold alongside Nintendo’s current Wii U and 3DS gaming devices. Kimishima did not give any details on the performance of the console, but he did say that it was meant to be a new gaming experience. This could allude to a more powerful console designed to be a better competitor against the Xbox One and Playstation 4, but it might also point to a unique new interface similar to the Wii’s motion controls or the Wii U’s tablet."
