What could the Switch2 'Gimmick' be?

What I would like to see:

1) Ditch the dock. - It's 100% unnecessary in a wireless world.
I have been able to "project" my phone and tablet to my TV wirelessly for a decade now.
- The handheld could then be used as a controller for asymmetrical gameplay.

2) Multiple form factors for multiple demographics, same software and hardware.
- Pure Handheld with a Base, XL and Lite model.
- Pure Home console.

Will wireless work from a bandwidth perspective?  As in 1080p, 30 fps and full surround sound?
