As we approach the planned March 2017 launch of Nintendo’s still-mysterious NX, a new report adds weight to some earlier rumors that the system will be a standalone portable with the ability to plug into an HDTV.

Eurogamer cites “a number of sources” in reporting that the system will have a built-in screen that is “bookended by two controller sections on either side, which can be attached or detached as required.” The brains of the portable system can then reportedly be plugged into “a base unit, or dock station” for display and play on an HDTV.

Eurogamer’s sources suggest the system will be powered by Nvidia’s mobile-focused Tegra line of processors. Development kits are reportedly built around the Tegra X1, which powers tablets like the Google Pixel C and Nvidia’s Shield Android TV console. That kind of hardware should be capable of decent 1080p HD graphics, but definitely won’t be a match for the kind of performance found on the Xbox One or PlayStation 4 (not to mention the upcoming hardware refreshes announced for both of those platforms). On the other hand, the power-sipping Tegra chip should be effective at extending the system’s battery life when it’s being used as a portable, and should help keep costs for the system relatively low.
