During the special livestream dedicated to the Dragon Quest series, in July 2015, Square-Enix finally announced Dragon Quest XI. Initially, it announced only for the Nintendo 3DS and the PlayStation 4… until Yuji Horii himself revealed during that same livestream that a Nintendo Switch (known as NX back then) version was also in the works.
But shortly after the livestream, Square-Enix sent a press release to explain that the Nintendo Switch version was not confirmed, and that the company was only “considering” it (despite Yuji Horii’s wording being as unambiguous as could be).
Following that, the Nintendo Switch version of Dragon Quest XI: Sugisarishi Toki o Motomete was again confirmed several times (in that interview, for example). In fact, Yuji Horii did mention it again during the Jump Festa 2017 presentation, last week.
And it looks like in the end, Nintendo gave up trying to keep the Nintendo Switch version of Dragon Quest XI: Sugisarishi Toki o Motomete a secret. Indeed, the company confirmed earlier today that such a version really does exist (though no details were given, such as the version it’s based on), ahead of the Nintendo Switch presentation on January 12-13th.
Dragon Quest XI: Sugisarishi Toki o Motomete (3DS, Switch) will be released next year in Japan.
