For Nintendo, they aren't quite intentional as the headline might suggest, but more of an intentional case in territories outside of Japan as they likely used some more supply in Japan as the two big games launched there. Globally, the only intentional shortages I can see occurring for Nintendo are when they skim a little hardware to stockpile for a release of a big title or divert some units to a certain territory for a release of a big title - otherwise I think they are easily shipping everything they have currently.
