Of course, the day before I give my presentation Scott Guthrie posts ASP.NET MVC Road Map.  I guess it's better than a day after, at least I could update my talk.  Scott links to his first five posts in the article so I won't include those.

In this post Phil talks about testing controller actions in the ASP.NET MVC Framework.  He has a couple more, one using RhinoMocks and one on testing routes.

MvcContrib is a good place to start looking for community supported additions, enhancements and replacements to various pieces of the ASP.NET MVC Framework. 

If you're looking for how a particular group of people are wrestling with the ASP.NET MVC Framework take a look at CodeCamp Server.  Jeffrey Palermo started it up and has a good number of blog posts working through some issues.  One of them is about SmartBag if you're interested in passing more than a single type of data into ViewData.

If that's not enough to keep you busy then check out ASP.NET MVC on del.icio.us.
