"What's the biggest improvement of Source 2 over Source?"

The biggest improvements will be in increasing productivity of content creation. That focus is driven by the importance we see UGC having going forward. A professional developer at Valve will put up with a lot of pain that won't work if users themselves have to create content.

Hopefully this means drastically better tools for us.
