The following excerpts come from Nintendo president Tatsumi Kimishima in regard to continuous Nintendo 3DS support:
Although sales are trending lower than last year, the results from our seventh holiday season sales have maintained stable levels. As explained during the financial results briefing in October of last year, the Nintendo 3DS family of hardware has continued to sell steadily without significant fall-off, even after the release of Nintendo Switch.
Overall totals for 2017 were down compared to 2016 when Pokémon Sun and Pokémon Moon had globally intense sales levels, but exceeded 2015 in the US and European markets.
A multitude of titles across a wide variety of genres have been released for Nintendo 3DS, creating one of the strongest lineups ever. We are, of course, continuing to develop new software, but we believe it is important to leverage the rich library of Nintendo 3DS series titles to drive sales with Nintendo 3DS owners, as well as consumers who recently purchased Nintendo 3DS hardware.
