We've heard plenty of rumors since then, including a console-handheld hybrid, a system more powerful than the PS4 and Xbox One, and a console with a bizarre touchscreen controller (including faked photos) based on Nintendo patents. The house of Mario has stayed quiet throughout, stating only that it will talk about the console later in 2016.
This might be the weirdest way anyone has ever announced a console. The company has confirmed that their E3 presence will include the new Zelda title and really not much else, including the NX. It's pretty strange for a system that launches in less than a year to not be shown off at such a high profile event.
