Timestamp is around 1:00h when she joins the podcast.
Syrenne is a registered Nintendo developer who's working on Monochrono for the Switch and Wii U.
She makes appearances on the RFN podcast sometimes and always gives some behind the scenes insight at Nintendo or the Japanese gaming industry.
While she's still under NDA and can't talk too much about technical specifications she did give some juicy tidbits that I thought were interesting.
I'm going to paraphrase for the people who just want a written version of what happened.
On Joy-con's
-Lots of tech
-HD rumble is the real deal. The bottom of the joycon will vibrate if an ice cube hits the bottom of the glass. And a full glass of ice cubes will make the top of the joycon rumble. Like the joycon becomes the glass. Basically the rumble can vibrate at different intensities but also at different locations instead of being one giant motor.
-IR pointer is great. It would be difficult to make Wii BC games work with it but not impossible.
-Comfortable to hold while separated and joined together. It doesn't look ergonomic but they fit in hands naturally.
-Motion tech is on par with Oculus Touch and Vive controllers. Very accurate. Way better than Wii motion plus and PS Move controllers.
-it detects subtle movements.

Why VC sucks on Wii U
Edit: I'm still listening to the podcast. Some more interesting tidbits.
Wii U never made money
Dock
Interesting comments about the accuracy of motion controls. I do wonder how they fight drift though (accuracy wise PS Move was already really accurate). Unless the console can provide a stable reference point for them, you would still need to reset their position often if you want to do any kind of 1:1 motion tracking.
