Sure, nobody has shown something like that in a single package for now, but FaceWorks works on a mobile GPU in real-time - so it's obviously feasible in VR on a PC - and real-time facial capture has already been shown in previous siggraph editions (see Oculus, Disney or Face2Face).
Again, I'm not saying that it's not cool, just that it isn't as impressive as the article makes it look.
