Game Director Takeshi Uchikawa mentioned that while the game is being developed separately for PS4 and 3DS, he’s working to create an enormous world that would not betray the expectations of the fans, hinting that the map size is going to be comparable to previous chapters of the series.
Within the final remarks at the end of the stream, Producer Yosuke Saito mentioned that the game is being developed with the thought that it would be nice to have it ready within the 30th anniversary of the Dragon Quest series. The anniversary ws on May 27th, 2016 (the first Dragon Quest was released in Japan on May 27th 1986), which would place the target release date before May 27th, 2017. This might be earlier than many expect, but the game did appear in quite advanced state of development.
Last, but not least, today Nintendo Japan published a news page showcasing only the 3DS version of the game, but confirming that that it is also planned for a release on the Switch.
This solves a small mystery that became apparent during the livestream and the following promotional materials, including press releases and the official site, with absolutely no mention of the Nintendo Switch made, despite the fact that it had been pretty much confirmed a few months ago.
It’ll be certainly interesting to see if the development team will manage to hit the anniversary target, which would put the release of the game in Japan within six months, probably earlier than what many would have guessed. Of course, since the panel was intended for a Japanese audience, this tells us nothing on when or if Dragon Quest XI will be released in the west.
