Jeff,
I will forward this on to the documentation team at Microsoft and see if we can have an overview of all the new technologies that we have coming out in the future.
Dynamic Data - This feature is an enhancement of the existin ListView, GridView, FormView and DetailsView controls that add new features such as: Templates to change their look and feel, Automatic validation (string length, null/non-null columns, datatype), converting foreign keys to nice text and dropdown list edits, this can be enhanced via metadata on the data model. Plus there is a scaffolding framwork that can be used to quickly build an admin type site with little or no code.
MVC - This is a new framework for writing application on the ASP.NET platform using the MVC pattern. This new model features a seperation of concerns, very TDDable and gives you full control over the markup. Today this framework is mainly for people building new website that want to take advantage of the items I listed. In it's first version it will not include controls, validatoin.
If you have any specific questions I'm more then happy to answer them
