Is it possible to dump the Wii U NAND (not the vWii NAND) using a soldered SD card adapter, just as is possible on 3DS? See http://gbatemp.net/threads/nand-flash-dump-3ds-xl.350668/ and http://gbatemp.net/threads/nand-flash-dump-3ds.353263/
I realise that there's no hack for the Wii U yet, but I still like the idea of backing up the current firmware now so that the console could later be downgraded, just in case.
