Nintendo can be tricky sometimes. Take Metroid Prime 4 for example: it was announced ages ago and even went through a full developer change! Breath of the Wild was officially unveiled in 2014, then missed E3 entirely in 2015 and was delayed into 2017. So sticking to "TBA" for games related to both of those franchises is smart. None of that has changed, but Nintendo has updated release dates for pretty much everything else, courtesy of their newest financial report.
Luigi's Mansion is releasing today, then next up we have Pokemon Sword & Shield,followed by Tokyo Mirage Sessions #FE Encore in January. Then there's Animal Crossing: New Horizons on March 20, 2020, which hopefully won't get delayed out of that time period like Last of Us II and Watch Dogs: Legion before it. But that's just the US region.
In Japan (as well as Europe a month later) Brain Training for Switch will launch on December 27, followed by a set of Famicom Tantei Club games in 2020. In case you forgot, those are a pair of almost lost adventure games created by Nintendo from 1988, which are getting remade on Switch. Given that they were only released in Japan a localization isn't likely, but hopefully it'll happen at some point so more people can experience an obscure moment in Nintendo history.
In all it's a pretty chill holiday period. There aren't a whole lot of games coming out after mid-November: no Super Smash Bros. Ultimate killer releases in December like last year.
