Mike Heskin, who has been known for finding little bits of code in the past has found reference to a new Nintendo Switch console in the firmware code. The console is codenamed ‘nx-abcd’ (which lines up with former codenames).
The biggest part of this finding however, is that the code refers to a new Nintendo Switch mode with a second screen. Now, this doesn’t necessarily mean that it’d be a Nintendo DS type device, but it could point to a second screen that is used for notfiications or something to that degree.
Firmware 10.0.0 adds preliminary support for a new hardware model: "nx-abcd". 3 of the 5 new DRAM profiles are for this new hardware type and there's evidence of a secondary display of sorts being added exclusively on this model. ( ?° ?? ?°)
It could also be something that never sees the light of day, but it’s interesting that it was there nonetheless. Both the Nintendo Switch Lite and new Nintendo Switch with improved battery were discovered this way before they were announced.
