Clearly my ability to inject humor failed. I did not mean to imply that Microsoft was doing anything either secretive nor nefarious.
My point was to turn upside down the common understanding that C# and VB2005 produce very similar IL, and rather to provide the perspective that there really is just one language for .NET (MSIL) with various flavors of syntactic sugar laid on top.
One flavor is reminiscent of C++ and Java, and another flavor is similar to (but notably different from) "classic VB."
Sorry if I was unclear.
