If Nintendo can hold 60 million userbase for Switch (about the same as the 3DS) that's fine. They're going to have to work harder because yes obviously the market for portable electronics and entertainment has radically changed the last 6-7 years especially.
20 million in Japan is the key, if they can have strong userbase there, they should receive a lot of Japanese support with a system (for a portable) as relatively powerful as the Switch is.
US/EU are probably tougher for Nintendo but they are larger market naturally, so that may balance out.
