While it shows nothing new about the console itself, Nintendo just released an English Switch Hardware Overview trailer.
Clocking in at just over 3 minutes, the video gives us a brief overview of the Joy-Con(plural) and their different functionalities. It also shows off the 3 modes of gameplay: TV Mode, Handheld Mode, and Tabletop Mode.
If you cannot get enough Switch media to consume, give this a watch. Otherwise, aside from a few seconds of new gameplay footage, there is nothing to see here for those keeping up with their Switch coverage.
