I want to step back a bit. All of these require a more involved and production ready asset system, which we've sorely needed for a few releases now.

I'm one of the two developers currently behind our longer term animation efforts, and I am keeping up with the state of the art in terms of animation compression, streaming, composition, and generation, but there's still a sizable amount of groundwork and plumbing before any of that can even be attempted. We definitely need a lot more eyes on this area of the engine.
