I think if you compare the enhancements C# has been receiving versus the enhancements VB.NET has been receiving from Microsoft you'll find that this is already happening.

I stand next to my hypothesis that C# was made to get support from lower-level open-standard types for the sole purpose of building the stage until it is ready for the proprietary technology, VB.NET, to become the star of the show.
