Nintendo:

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.

Nintendo Switch (formerly known by the code name Nintendo NX) is a gaming system that embeds a portable system into a dock, making it easy to switch between console and portable without exiting your game. I look forward to taking this system for a spin, playing the next-gen Zelda title on the road.

From the Nintendo Switch Wikipedia page:

The Nintendo Switch is described as a console/handheld hybrid system, allowing players to alternate between playing on a television via a docking station and playing on the move using a detachable screen. Along with supporting wireless game pad controllers, the system comes with detachable controllers which can either be used in tandem with each other, either connected to the screen or used in each hand similar to the Wii’s Wii Remote and Nunchuck control scheme, or can be used as two seperate sideway controllers for multiple players. The game will also feature wireless multiplayer via multiple systems, for example, allowing four players to play using two Switch systems. Games played on the system are distributed via cartridges and digital downloads.

Enjoy the trailer.
