Let's not forget that there is still a Kinect SKU and standalone Kinect coming in the fall.
But I'd say there is no benefit other than a competitive price. The fact that they dropped the price and Kinect together will be a huge factor for those who have not yet purchased the Xbox One but are Xbox fans. (Like myself. To be honest though, I want the SKU with Kinect).
