The professional video tutorial scene has started to adopt XNA from the looks of it, with Digital Tutors releasing a DVD training package named Pipeline Development with Maya and XNA.
Popular highlights:

CGSociety has this to say about the product:
'Pipeline Development with Maya and XNA' contains nearly five hours of project-based training for technical artists learning the methods of creating game content using XNA and Maya. 'Pipeline Development with Maya and XNA' offers artists an essential workflow and innovative techniques for easily integrating Maya and XNA for game creation.
Since this costs money, I cannot get this at the moment and so I cannot give my own review. However it looks like a good product, and considering Digital Tutor's track record, it should be a good investment for the artistic programmers out there.
Edit [17/5/2008]: I noticed that Digital Tutors also has an interesting looking Training Package titled Real-Time Shaders with XNA.
