Citar:
* Razor View Engine which ScottGu wrote about recently. Note that for Preview 1, we only support the C# version (CSHTML). IN later previews, we will add support for the VB.NET version (VBHTML). Also, Intellisense support for Razor syntax in Visual Studio 2010 will be released later.
* Dependency Injection hooks using service locator interface. Brad Wilson should have a few blog posts on this over the next few days.
* Support for .NET 4 Data Annotation and Validation attributes.
* Add View dialog support for multiple view engines including custom view engines.
* Global Action Filters
