If you’d have asked me last year, I would’ve never guessed that Zumba Fitness: World Party would kill two career mini-milestones at once for me: the first time I got to physically pick up and hold a real Xbox One, and the first time I got to see a Kinect 2.0 motion-controlled game in action.*

“ Believe the hype: the new Xbox is almost inaudibly quiet when running.

The art style is an interesting mix of live-action and animation.

“ Seeing the two Kinects work at the same time in the exact same space was telling.

Whoa, I've been to that beach in Hawaii!

And work it does. The response time on Kinect 2.0 is very obviously much faster than the first Kinect, which Majesco made obvious by switching back and forth on-the-fly between Xbox 360 and Xbox One builds of the game (because certain sections they wanted to show me didn’t work properly on the One yet). Seeing the two Kinects work at the same time in the exact same space was telling. Input lag is no longer noticeable – that’s not to say it isn’t there because, well, of course it is – but it no longer feels like you’re fighting the Kinect to get it to read what you’re doing.As for Zumba Fitness itself, you may know the story. The Latin-born, DVD-based workout craze brings a simple philosophy to its “exercise in disguise”: you do the same simple moves with the song’s chorus, and another set of actions during the verses. The idea is simply to move rather than be doing specific choreographed dances a la Dance Central, and you know what? It seems fun. Everything from Lady Gaga’s “Born This Way” (seemingly required in any dance/fitness game) to Hawaiian luau music is here, resulting in varied workouts that end up working different muscles.Should you get hooked on the Zumba craze, the game will even go so far as to tell you where the nearest real-life Zumba classes are available in your area.The Xbox One version, for what it’s worth, will include extras besides a vastly superior Kinect camera. Additional songs and dance styles will be included in the next-gen edition, though you’ll have to wait a bit longer for it. It’ll ship sometime “within the Xbox One launch window,” but after the 360, Wii, and Wii U editions drop this October.Kinect 2.0’s first real hands-on test is expected to take place at Gamescom, where I’ll be playing Kinect Sports Rivals. More on Zumba Fitness and Kinect 2.0 very soon.

*Just to prove how weird I am that I tend to remember these little bits of personal video game trivia, the very first Xbox 360 game I played was an alpha development kit build of Top Spin 2 in 2005. You'd never guess that game, right?
