"Dragon Quest creator Yuji Horii had a charming message for fans near the end of 2019. Within the message on Twitter was confirmation that development for the next main Dragon Quest game started last year.
The full message from Horii's Twitter account can be found just below. The translation comes from Twitter user @BlackKite.
Happy New Year. Last year we started with publishing the movie Dragon Quest: Your Story, then releasing the Switch version of Dragon Quest 11, the mobile version of DQ Walk, the announcement of The Adventure of Dai anime along with its game adaptation, the production of [DQ]12 and more; even now after 33 years have passed since I made the 1st game, I feel very glad that I can do new challenges like these. Thank you very much to all users who have cheered on Dragon Quest until now, and also to all of the many staff members who have supported me. I don’t know how long I can go on, but I feel like I want to do my best just a little bit more. I hope this year will be an amazing year to everyone. I’m looking forward to work together in this year.
Confirmation of Dragon Quest 12 shouldn't come as a massive surprise. Two years after it released in 2017, Dragon Quest 11: Echoes of an Elusive Age shipped more than 5.5 million copies worldwide, on PS4 and Nintendo Switch."
