A few things on VB not getting refactoring:
Sam Gentile has an interesting inside view
Julia Lerman points to the VB.Net blog that started it all...
It looks like VB.Net programmers who really want refactoring will have to buy it from someone other than Microsoft...like NET Refactor. It works with both VB.Net and C# in VS 2003, so why wait for VS 2005 to refactor - do it today
