Agree with most of what you said.
Don't think western third party support will dry up because I think developers will be very selective to begin with. So no Mass Effect Andromeda from EA but Maybe Need for Speed, The Sims, Garden Warfare etc.
I think it will comfortably outsell Xbox One.
The name Switch is growing on me.
With no interface/controller gimmick, I have a feeling the NS may present a rising tide for PS4 where Japanese Software is concerned. I.e Bravery Third, Monster Hunter, Yokai etc may find their way to playstation.
On a slightly unrelated note, I've decided I want them to come in at $300. Don't take any shortcuts with hardware & Manufacturing.
