As blogged before you know that I think DevExpress CodeRush totally rocks!
Did you know that you can get a lot of this functionality for free?
Mark Miller has got a very nice list of features that are available in CodeRush Xpress for C# and Visual Basic inside Visual Studio 2008. All for free!
In the full product you will get even more, check out the differences in this article: Moving up from CodeRus Xpress to CodeRush
The downside of all this good stuff is that Delphi Prism is not supported. The fact that the original CodeRush was a pure Delphi IDE product, I can not believe that it will not be supported in the future.
