I'll be getting them all, and I'll be pre-ordering on 7/4. I learned the hard way, via the Intensity Series, that you end up buying them all eventually anyway, at a much higher cost (plus additional shipping). Then for some reason, I missed the early Body Blast pre-sale and ended up paying abit more at the end of the presale.
By the way...once you start using premixes, you'll love them and use them all the time. I usually use the workouts as is for a while, until I get the step/moves down, and then I venture into the land of premixes.
