The Xbox cloud streaming device codenamed Keystone will need more time in the oven before it can be released, Microsoft confirmed today.

In a new statement provided to Windows Central, a Microsoft representative described Keystone as an integral part of the company's plan to eventually let users play games anywhere they want and on the devices they want. The company, however, made the decision to "pivot away" from the current iteration of the device.
