When will we see Dragon Quest XI release for the Switch? We honestly have no idea, but at least there's a small update from Square-Enix themselves. Series creator Yuji Horii has said that development on the Switch version “is going well.” Horii hopes he will be able to share more details soon.
Here are Horii's full comments, which seem to tease something for TGS.
“I can’t really talk about it much, but I can say that the Switch version is coming along nicely. You know, there are a lot of possibilities at TGS for all kinds of announcements… Hmm, what else can I say?”
