Taleworlds released a video yesterday talking about their development process for Mount & Blade II: Bannerlord, showcasing the environment their 49-employee team works in and what is being done with the game.
Unfortunately all media shown of the game are old screenshots visible on their oft forgotten blog and the video does not contain any in-game footage of Bannerlord as of yet. Key points include their in-house engine development, the motion capture, and their AI routines.
Mount & Blade II: Bannerlord is currently in development for Windows PC.
