New TF2 Machinima tools on the way?

An interesting blip over on ShackNews: it sounds like Valve will be releasing some new machinima-focused/friendly SDK tools that were used in creating their "Meet The ____" series of shorts around Team Fortress 2. The post by a Valve employee (signed Robin - I'll assume it's designer Robin Walker) makes mention of the tools, though its timeframe is a bit indefinite (sigh). He doesn't get into specifics around what tools these will be, but I imagine they're most likely pipeline/middleware stuff that allows transparent production between Maya/XSI and Source.

With Hammer/ModelViewer/FacePoser already supporting TF2, that seems to be the missing link in the SDK. However, this blogger is hoping for something more along the lines of Demo Editor/Smoother 2.0 or the like.
