Xbox, Infinity2.0 and Rush Kinect experts-help

[DCbride]

I would like to buy DD7 an Xbox. We have the original Wii and Infinity 1. I would like to get her the Rush Kinect game and Infinity 2.0. Which system do should I buy? The Rush game needs Kinect, but it is for Xbox 360. People suggest getting the Xbox One because it will "last" longer.

Any advice on what to buy, what I need (extra controller, battery charger, buy Kinect separately) I am so confused and could use the advice, since I would like to purchase today or tomorrow.

Thanks!
