I finally found some time to post a webcast I delivered a little while ago showcasing some of the new features in Dev11 and TFS11. I do some quick demos of Storyboarding, Agile Project Management, Code Clone, Code Review, Feedback manager, and lastly IntelliTrace in production. You can find the recording here.
If you would like to try the demos yourself, you can download the VM and the labs here.
You can also download just the dev11 or tfs11 beta bits here.
