Where should I start Game Dev now?

So, I have CS degree, MMO dev experience in a native language (think WoW and its scripting language (LUA?), except standalone,) and a lot of 2D games developed in C# XNA.

I want to move to C++ but I'm not sure where to start. At the moment I'm looking at GameDev.net.

Hmm. But the problem is that there are no straight up education programs or credentials I know of that are solely for teaching you how to create/design games. So I don't know what else to do other than comp sci or programming
