Definitely Imax 3, as long as there are new creative moves. I'm really tired of the same plyo jumps, power 15's and mambo cha chas. So I'm hoping for fresh stuff. This series seems pretty quick and I hope she can be creative in that short time frame. IMO, if she plans on doing all these workouts, she would need a year to come up with new stuff, but then again that woman always amazes me.
