This patent also came true it seems (sensor/camera on the side of the Joycon). 

Well done, dude :)

"And then there’s HD rumble, a concept that uses vibration technology to simulate a new type of force feedback. In one demo, I was shocked how well it conveyed the feeling of spheres sliding around inside of a mystery box. As I tilted the controller back and forth, I could feel the contents rolling up and down in the palm of my hands."

Now this has me excited.

Very nice one! And same here! I am excited now after reading and watching people's thoughts on it (the ones who tried).

The one I recently watched from Easy Allies also said how he can really feel the balls moving and hitting each other on 1 2 Switch. And milking too. And how that cutting puzzle game, how he felt like getting pinched everytime they cut each other (lols).

They are packing soooo much things into the Switch! Motion + Rumble + That sensor/Pointer + The Switch and Play! I am feeling more positive on the switch.

I'm going to go watch the Easy Allies video now. Sounds cool.

I think it's a feature that's not fully understandable until you actually use it in person.  It's probably one of the reasons why a lot of people are bemoaning over Nintendo not putting 1-2-Switch as a pack-in or pricing the game more aggressively because it would do a good job at pushing the virtues of HDRumble when playing it at parties and gatherings.  Who knows, HDRumble might be the missing piece that motion controls need for it to be accepted as something more than a gimmick.  Personally, I love motion controls when used as a pointer device since it works better than gamepads for certain genres like FPS and RTS.

I think later on, maybe  by holidays 2017  1,2 Switch will become a pack in game in some new holiday bundles. The game is literary a pack in game that is not pack in at launch for some strange reason. Maybe  1,2 Switch was going to be pack in at launch but Nintendo decided to sell it stand alone to help fill the Switch's launch library?

Nailed it.
I will look really forward to it.
You will be able to feel different kind of textures, and could touch a wall for looking for a switch or something.
They could do some really cool stuff with it.
