No one shall be brought before our LORD David Bowie without the true and secret knowledge of the Photoshop. For in that time, so shall He appear.
As a few had already speculated, it seems like there’s an optical sensor in each of the Joy-Cons, just like the ones used in computer mice. We even see the Joy-Cons scooting around on a surface in the trailer, essentially confirming the functionality.
It makes me think we’ll see games that utilize the Joy-Con as a mouse, which could be cool for more PC game ports. But what I’m really hoping for is Mario Paint 2.
All that being said, this seems like an awkward way to control something in-game.
