I'd like to know what kind of C++0x support you're aiming for in the long term. Browsing through the minutes of the C++ committee meetings, it looks like Microsoft has attempted to veto a handful of proposals, with varying success. In particular, it looks like MS refused to ever implement the new attributes, even though they were accepted into the standard in the end. Is that decision final? We're never going to see a compliant implementation of C++0x from you?

As for your prioritization for VC10, I think you've made some sensible choices. Shame so many features had to be left out, but given that you're targeting essentially the same launch window as the new standard itself, I can't blame you.
