It definitely looks like the same thing in the Lenovo Legion Go which has the detachable controller usable as a mouse .

Also the shipment parts leaks apparently have listings for "mouse sole" for the Joycon, yeah think a mouse functionality is happening:


Also this one is NOT REAL, just a fun mock-up of what the box could look like with the orange/blue + matte black console color scheme and new rounded dock design

That's interesting. I hope that feature works well on the Switch 2 if it's a real feature.

I need ro see the buttons why couldn't this man flip the controller.

Apparently the front of the controllers look like this, there is a small color accent below the analog sticks but no colored buttons, according the NextHandheld leaker person who leaked a bunch of stuff that's been coming true. (mockup by Necro Filipe of UniverNintendo):

Nah, it's those back buttons I need a look at. Fairly sure this thing will have adaptive triggers like the Duelsense/PSVR 2 controllers. 

Haven't looked into the validity of this one, so I don't have a stance on that. But here's a mock up comparison with Switch 1.

Seems taller than the Switch 1 Joycon.

That's because the Switch successor is also larger than the OG model.

Mouse capability would be nice for games like Torchlight which is already on Switch.

That sounds good, but having more power than the OG would be better.
