Given that people were buying stolen Switch units and unboxing them online already, it made sense for Nintendo to follow suit.
There's not much of a surprise here - it's an unboxing of the Switch, the parts of which most people are familiar with by now. But if you missed what leaked online, then the video below is a good opportunity to catch up.
The box is split into two layers, with the cabling, some minimal documentation, the docking station and the Joycon grip on the bottom. There's a HDMI cable and the adapter down there as well.
The guts of the box, pictured.
A single Joycon pictured; you can make out the pairing button in the middle.
You can see the adapter here; it's not too big.
