Okay here's my serious hot take on the Switch situation. Now that there is a price and a software list and everything is in the open, I feel this speculation will make a lot more sense.
Right now the Switch is absolutely a home console and this is very important for Nintendo. This is their replacement for the WiiU and they need it out asap because the WiiU is a rotting corpse. Everything they have announced at the conference thus far points to a console level launch in March, followed by the support of console titles throughout 2017.
Why? Because they are still selling the 3DS and their partners are still releasing 3DS games in the near future. This will change drastically by October 2017. The Fall Nintendo Direct will move towards the next stage of the Switch branding. It will move to replace the 3DS in 2018 and beyond as the portable of choice. They will offer a lower priced Switch as a portable without a dock, possibly at as low as 20,000yen. They will also begin to announce portable centric software which directly replaces 3DS titles - Monster Hunter, Pokemon, Level5 games, etc.
Will it work? Who knows, but I'm 90% certain this is the strategy moving forward.
