Let me just preface this by saying that I think the artist did an amazing job putting this together. They are truly talented!
But ever since this artwork surfaced, people have been saying that we should get a frozen region. It's just been a bandwagon that many people have hopped on... Similar to the Man O' War.
To me, it makes absolutely no sense at all to have an ice region in this game, and I absolutely do not want to see snow and ice when I'm playing a pirate game. The Devil's Roar does make sense, but this frozen glacier thing is just completely out of place for Sea of Thieves, and I really hope that Rare do not spend their valuable time and energy to create something like this in a game where it would not be fitting at all.
I would much rather they go on to flesh out some of the regions that were talked about in the Art Book, like the Sea of Five Winds.
