Ryslaw Chojnowski
As a reminder, the same person who first leaked that Kingdom Comedy creators were working on Lord of the Rings confirmed the DLC for W3 after Boris's words. He also worked on W1 back in the day :)
Edit
Rysław, during a live broadcast with Kingdom Come, made an important point: This DLC is definitely in the works, and many people around him have confirmed this. The problem is that it has to pass Cdpr's review. It has to be good enough for Cdpr to approve its release, as the bar for the previous two is high. If Cdpr doesn't like the DLC in the end, it can be cancelled, as it doesn't officially exist.
