The Switch being marketed as a Home Console is strictly due to western markets. Consoles clearly have a hold over here compared to handhelds and Nintendo wants to make sure this system succeeds.
I fully expect NCL to market this thing as more of a handheld with a TV out in it's home market.

There are three things wrong with that:
1) The Wii remote in general is tied into the Wii branding. Nintendo wants to move away from it.
2) The Wii remote is also over a decade old.
3) The Joy-Cons look similar and have many of the same functions as the Wii remote.
I agree Nintendo should keep functionality of them for now, but eventually, they will start phasing the Wii remote out.

Wait, wait, wait. You think Nintendo hasn't handled multiplayer games well in the past?
Online multiplayer (although Nintendo has been doing better with Mario Kart, Smash, and Splatoon) and asymmetric local multiplayer on a console I'll give you, but local multiplayer has been a strong point for Nintendo's systems, especially since the N64.
