Arkane Studios are currently celebrating their 20th anniversary. For those interested in the creators of the Dishonored series, Bethesda is publishing several articles retracing their work since their first game, Arx Fatalis. They also put a newsletter which gives you access to a short PDF artbook containing concept art of both Dishonored 2 and Prey (I'm pretty sure they can all be found in these games' respective official artbooks). More can be found on this website, including links to the Bethesda articles I mentioned: https://bethesda.net/en/hub/arkane20
Also, the Youtube channel NoClip recently released a long documentary on Arkane's history, including interview of its founders and developers about their experience during these 20 past years and exclusive gameplay footage of 2 aborted game projects: https://www.youtube.com/watch?v=h4kdqwdbZZ8
There doesn't seem to be anything new regarding the Dishonored series, but those are still interesting for anyone curious about game development in general.
