Today Microsoft released a preview of the Visual Studio 2010 with partial C++0x support. This should be also based on their new, Phoenix based compiler, and brings the most important features like
auto, rvalues and lambdas. There is a post about some of the new features at the Visual C++ blog. Moreover, it seems to get some parallel helper library, similar to the thread building blocks, both for managed and for native code. Looking forward to this as well.
Great time to be a C++ developer right now :)
