While I think dodgeball has always been 3-D (even in the normal school yard version, it's not like you're rolling the ball, after all), any excuse for adults to jump on trampolines is one I'll gladly take.
Mostly, this version of dodgeball reminds me of Slamball, which was on TV for a little while, which I don't nearly have the athletic talent to play. Throwing a ball and falling down on a bouncy surface? Totally do-able. Jumping up in the air and trying to slam a basketball? Nope, not going to happen:
