It indeed looks like the development of C#/VB has slowed down since they began working on Roslyn, but it makes sense. They obviously can't finish a much more sophisticated compiler than the one they developed for 10 years in C++ overnight, I'd guess it might take another 2 years or even more before they can finally put the old one to sleep. After it's ready however, it'll be much cheaper for them (and possibly even for the community) to add new features to C#/VB, while providing tons of additional useful services. Don't want to discuss my ideas about them right here, because I don’t have enough time, but –if they make it right- its impact is going to be huge :-)
