Rumors about the Nintendo NX, the company’s Wii U successor, have been swirling since the project was formally announced in March 2015. Thin supposition has turned into more concrete, sourced reports that the NX is a handheld with living room capabilities.

The latest report comes from Eurogamer, which claims sources have revealed a number of details about the hardware. According to the publication, NX’s handheld form factor will have controller attachments on each side for use with a television or monitor.

The controller dock would be required for use in the living room, and Eurogamer’s Digital Foundry suggests that the handheld uses Nvidia’s Tegra mobile processor. Another refrain in the story is that the NX will use cartridges rather than discs.

This fits with Nintendo’s handheld strategy, of course. 3DS users are no strangers to small game cards. The NX will also support digital copies, similar to the Wii U and 3DS.

According to Eurogamer, Nintendo is scheduling a formal console announcement in September. NX is due in March 2017.
