Correct, a procedural scene is a much different beast from a static geometry scene as far as previewing and GPU-based computation go. We do have plans to multithread the 3D preview in the future, which will certainly speed things up. Right now, as you know, it just uses a single thread, so those of you with 2, 4, 8, or even more threads to use will eventually see a dramatic speedup in the 3D preview.
As for the animation module, we don't have a release date at this point (unsurprisingly). We will of course update everyone as soon as we can provide more information. We've been as open as possible about the features that can be expected.
