Very interesting changes in ASP.Net MVC 3, the razor engine is a welcome addition. While it is a different way of coding, it has a hint of the throwing ASP and C# together. A WebGrid has been added to the controls, much needed in my opinion.
But do not take my word for it you can read all the details at Scott Guthrie's blog and Phil Haack's blog posting.
Last but not least a roadmap for ASP.Net MVC is available as well.
