I bought a new Nintendo Switch today. I'm pretty certain that it is the v2 as I bought the one with a red background on the box. As I was looking stuff up about the device, I found out that the serial number on the v2 switches start with XKW but my switch's serial number starts with XKJ. I am a bit confused as to what the deal with that is. I tried searching for answers but couldn't find anything conclusive about the matter. Any help will be appreciated.
