If you buy the downloads the Workout Blender will give you endless options for creating your own premixes, so the argument could be made that DVD's will have less content than you can create with downloads and the Workout Blender.
ETA that the Workout Blender, once it's released, will be free!
Will the "bonus" materials be included in the downloads for us to make our own pre-mixes? I believe the description of Intensity said the premix will include additional lower intensity material.
