You can get the same results with Poser/Daz (pretty much anything with a timeline) the quality of the renders looks more like Poser 7 or before. I see he also uses actual footage in some of his videos and merges the 2.  I would say if you want to make the same type of animation as that then get Poser or Daz, V4 and a product like this : http://www.renderosity.com/mod/bcs/rg-breast-jiggle-system-for-v4s/77394

 

That type of work is fairly simple for the most part. I can't say that he is actually using Poser or Daz, for the models are not familier to me. But you can get the same results and better with the newer versions of either software. I would actually suggest Poser 9 or pro 2012 over Daz for animations, you have better control.
