In addition to announcing Dragon Quest Builders 2, Square Enix made several other announcements during Dragon Quest Summer Festival 2017 in Tokyo this weekend which will affect a ton of the Dragon Quest properties, including Dragon Quest X the franchise MMO.
The fourth major expansion for Dragon Quest X, called 5,000 Year Journey to a Faraway Hometown Online was announced this weekend (with a translation courtesy of Gematsu), and will be released in Japan on November 16 for PS4, PC, Switch and Wii U for ¥3,800.
In Japan, the fantasy MMO will finally launch for PS4 on August 17 and for Switch on September 21. So new players will have a little bit of time to get into things before the new expansion hits, though it will probably be a bit of a crunch.
Square Enix also announced the card battle game Dragon Quest Rivals will be released for iOS and Android in Japan sometime this fall, and that a PC version is currently in development. The PC version will naturally launch sometime after the mobile release, likely closer to the end of the year.
And in case that isn't enough, Square announced that Dragon Quest and Dragon Quest II will be available digitally for PS4 and 3DS in Japan on August 10 for ¥600 and ¥850 respectively. Dragon Quest III will arrive later this month for ¥1,500. So, Japan might be seeing all of the main Dragon Quest games coming to the PS4 and 3DS in the coming months, which is fantastic news. What would be better is if those re-releases also made the jump to the West, but Square announced nothing on western releases this weekend, for obvious reasons.
That being said, the franchise's latest installment, Dragon Quest XI, launched last month in Japan and has sold incredibly well. And DQXI is indeed coming to the west in 2018.
