Cardio Fusion is a new DVD that was given as a gift to the people who preordered and kept their preorders despite the long wait. Basically it is a workout that includes cardio from Body Max 2, Low Impact Circuit, and Drill Max. SNM stated that it will be for sale soon. Here is the breakdown on the back of the package:
Warm-up from Body Max 2 9.5 min.
Body Max 2 Finished Combos 6 min.
Low Impact Circuit Bonus Combo 11 min.
Body Max 2 Power Circuits (don't do the parts with weights) 16 min.
Six Drill Max Drills (just the cardio portions) 22 min.
Stretch from Body Max 2 7 min.
You can just use all these parts from the three different DVD's if you don't have this DVD. Hope that helps.
