Firmware version 10.0.0 has brought a few welcome changes to the Nintendo Switch, not least the ability to remap Joy-Con and Pro Controller buttons. However, version 10.0.0 also hints at new Nintendo hardware being in development. There has been plenty of talk of Nintendo developing a "Switch Pro" before, but this is the first time that we have heard of a third device being referred to in Switch firmware.
Brought to our attention by Wccftech, the information comes from Mike Heskin, the same person who spotted that Nintendo had added support for a revised Switch in version 9.0.0. According to Heskin, version 10.0.0 adds preliminary support for the "nx-abcd", a model based on the Tegra X1+. Apparently, the "nx-abcd" includes a "secondary display of sorts", too.
While the Tegra X1+ would effectively limit the "nx-abcd" to maxing out at 1080p, the secondary display has got people talking online. Using our imagination, could the "nx-abcd" feature a Wii U style controller, or maybe a second screen implementation like the Nintendo DS?
There may even be a fourth Switch model in the works, too. Apparently codenamed Calcio and "nx-abcb", the model is a traditional console, meaning that it would only run in docked mode.
Tempering our expectations somewhat, Nintendo has publicly confirmed that it has "no plans to launch a new Nintendo Switch model during 2020". While that statement does not rule out Nintendo launching new models, we may to wait until 2021 before the "nx-abcb" or "nx-abcd" do arrive.
