To me the news that Foxconn is building up production capacity in Vietnam for the Switch of 4 million units annually seals the deal. Obviously we do not know what model Switch it will be. Perhaps only the Lite system, a budget revision, who knows? But it indicates that at least some of the Switch family of systems will be produced for quite a while. This sounds like the original Famicon scenario to me, where the Switch will get a lonnnnngggggg life.
