Hi there lorca!
This is what BGS Game jam is all about - Todd's keynote at DICE 2012 : http://www.youtube.com/watch?v=DGIgXeGC6Dg
OMG, I guess people were right about Skyrim being unfinished. All the features in that video should have been in the game before it shipped. If some don't make it to see the light of day, it will be a BIG disappointment because Beth has shown the ability to do many advanced shaders and if they don't do it, it will be very sad indeed.
I'm getting a feeling that Beth created this video to show folks who are complaining in the forums that they are capable of doing things that other game companies can; that they have the talented programmers that can do current graphical techniques.
