I did saw that Square Enix just announced 6 Dragon Quest games on the official Dragon Quest 35th Anniversary Stream. Dragon Quest XII is the next installment is happening. Dragon Quest III (Arusu's game) is getting a HD-2D Remake that the layout is similar to Octopath Travelers. Two Dragon Quest X games announced (Update Versions 5.5 to 6 for Online and newly announce Dragon Quest X Offline). Erik from Dragon Quest XI is getting his spin-off called Dragon Quest Treasures. A mobile Dragon Quest spin-off game for iOS and Android. I'm more excited for Dragon Quest XII. Dragon Quest III HD-2D Remake looks pretty good, but sadly that I already got Dragon Quest III from the Nintendo Switch eShop from the Square Enix sale last year.
For watching the whole stream for the announcements, just skip it towards 23:40.
