The response to the CBA case study has been simply overwhelming. The first video has many thousands of downloads and now I have 2 more finished. You can see them (along with some other case study videos) at http://www.ronjacobs.com/lwcs/ComSee.htm
Yes - these will be published on MSDN eventually but these things take time. If you want to see them now, check out my site.
Also - for those aspiring architect types out there I have a page for you - http://www.ronjacobs.com/Noodle/default.htm has a lot of great content for learning about architecture. More is being created every day so stay tuned.
