Just another 11 months of this and then the 3DS will be laid an honourable rest.
The Switch is Nintendo's future [I don't believe we'll see another unique HW concept again - complementary and experimental accessories aside], as are system upgrades every 2-3 years for all the big 3, imho.
Agreed. He clearly says "we think the Switch and 3DS can coexist for the time being". For the time being means for now, and implies at some point it won't. I think they're keeping the 3DS around because it's cheap, and the Switch is rather expensive for a portable. I think once it drops into the $200 price range and if it's selling well (which may only be 1-2 years), the 3DS will be phased out.
