Nintendo finally took the veil off of the "NX" today with the reveal of their new, upcoming console, the Nintendo Switch. Set to arrive in March 2017, Switch looks to combine the worlds of a home console with the portability of their handheld devices thanks largely in part to a modular design.
Introducing Nintendo Switch! In addition to providing single and multiplayer thrills at home, the Nintendo Switch system also enables gamers to play the same title wherever, whenever and with whomever they choose. The mobility of a handheld is now added to the power of a home gaming system to enable unprecedented new video game play styles.

The premiere trailer for the console shows off what looks to be new entries in some of Nintendo's most popular franchises such as The Legend of Zelda, Mario, and even Splatoon. I am sure we'll have more details about the console and new software very shortly.
