Along with the announcement of Dragon Quest XI, Square Enix also revealed this morning that a PS4 version of Dragon Quest X is currently in development. Just like Dragon Quest XI, Dragon Quest X is also "under consideration" for release on Nintendo NX.
"Dragon Quest X Online will celebrate its third year since release this year, but with Dragon Quest approaching its 30th anniversary, there is still more to come," said Yosuke Saito, the game's producer.
Dragon Quest XI is currently available on PC, Wii U, Wii, Nintendo 3DS, iOS and Android in Japan, however, none of these versions made it to the west. Considering how well the PS4 is doing worldwide, it wouldn't be a surprise if the PS4 version turned out to be an exception.
