Anyone who knows what is in the next major version of After Effects also knows to not publicize this information at this time.
So, I would advise you to not trust information like this from sources other than Adobe.
I saw this demo about a year ago. There's nothing to suggest that the demo involves AE. If I remember right it was a university research project. While there are some interesting approaches to solving some issues I don't think you should infer that it's going to be part of a new Adobe product just because someone put After Effects in the title of a video they borrowed from somewhere else on the net.
The only rumors about new features in upcoming builds that you can put any faith in are those that come from the developer...
Take it for what it is - a university research project. Nothing more. nowhere does it ever say that this would be a usable product or part of a usable product.
