In an interview with EDGE magazine, Dragon Quest XI executive producer Yu Miyake provided the first tease of the game getting a western release.

When asked about the series’ appeal in the west compared to Final Fantasy, Miyake said:

We’re still trying! [Laughs] It’s a topic we have been thinking about a lot internally: the question of why Final Fantasy is so much more popular than Dragon Quest in the west. […] One thing that does stand out: in Japan the target audience for Dragon Quest is vast. It ranges from primary-school students to people in their 50s. Now, Akira Toriyama’s art style is cartoonish, and in Japan that doesn’t alienate anyone; it’s not seen as childish.

But outside of Japan, I think there’s often a stigma attached to that kind of aesthetic. Now, when an adult tries the game, they will discover that the subject matter is actually quite mature. Nevertheless, players are still left with this disconnect between how the game looks and how it plays. That’s a tension that just doesn’t exist in Japan. What we’re seeing now is that the age of people who are playing is rising. Interest is also increasing. We’re trying to put a lot more effort into promoting overseas the spinoff titles we’ve been working on – Dragon Quest Builders and Dragon Quest Heroes – in order to soften up the ground for Dragon Quest XI.

There was also a tweet made by Square Enix (EU) that confirmed Dragon Quest XI for USA and EU for the end of 2017, but it was swiftly taken down soon there after, according to French website: Dragon Quest Fan

The issue with Dragon Quest's appeal to the west was the fact that they quit during the crucial era of the SNES. Final Fantasy didn't do well in the US either but they made sure the SNES games were localized. Around that time Enix of America had gone belly up until 2001 with the release of DQVII. If Dragon Quest V, VI, and 3 Remix were localized, I think Dragon Quest would have done much better than it is doing now in the west. However, the last 2 mainline Dragon Quest games did fairly well in the US and EU with VIII and IX both doing over 1.2 million in sales. Heroes has also done 250k across US and EU which is pretty good for a spinoff.

Hopefully the Switch version of Dragon Quest XI is based off the PS4 version. That'd be glorious.

Welp, I guess we can already prepare for realistic graphics and boy band fun in DQ12.

There's absolutely no reason to doubt the localization of Dragon Quest XI lol

Well last gen kinda sucked with localizations. 

But yea i have faith in sqaureenix. 

Dq xl looks amazing 

This is not news. We just had Heroes and Builders, games made with hyping the west up mind.

I think the PS4 release has a lot to do with trying to get more sales from the west

Are implying that its uncertain that the game will release in the west?

I doubt it would release in the west this year. We havent even seen any gameplay

What exactly does that have to do with anything?
