Nintendo NX has been revealed to be the Nintendo Switch, a console designed for playing at home on your TV, and on the go. It is powered by a custom NVidia Tegra GPU, and features cartridges instead of discs. Two detachable controllers can be taken off and slid onto a screen, and this combination can be taken on the go. A standard controller for use at home is also included for players who would prefer a more normal gaming controller.
