For those interested. At this point almost everything about this console has leaked. You can see the dual color inside magnetic rail. 

It explains a few things too.... like the leaked drawing with that plus icon, being the magnetic release button.
The leaker that mentioned "the color scheme is "below the surface".

Switch 2, will look more "adult" than the 2 color scheme the original switch had.
It'll look more premium, and nicer.

I'm also sure Nintendo will do joycons in different plastics that come in different colors.

Looks like the above is the left Joycon and below is the right Joycon with an orange interior mag rail



So matte black with baby blue and orange accents, that NextHandheld leaker person got that correct.

this is one of the most painful waits ive ever experienced for anything gaming related (besides Zelda TotK). Nintendo needs to cut it with this cruel tactic of drip-feeding a starving populace of Nintendo fans. Just reveal the system!

As long as they fix the stick-drift, I'm good with whatever lol

People are speculating that there's a optical (?) sensor there for a mouse mode for the Joycon.



You can see it there above the middle docking port, it looks just like what's on a modern mouse.

It would be used like this:

I tried this with my current Joycons and yeah it would totally work.

It seems like the Switch 2 will get an official announcement very soon, since leaks are getting bolder. There is even an accessories maker that will host a Switch 2 presentation on January 7th. The reveal should be very soon.

Nintendo sure likes to bring back every kind of idea huh.

Of course nowadays it'd be wireless, especially if they ever rereleased Mario Paint and/or Mario & Wario, the only games I can remember offhand that used the Super NES Mouse.

Still I'd rather hear from Nintendo themselves instead of having to go by all these iffy leaks.
