"We leaked it to the community because if something is shared then.. progress is achieved faster than alone. Something kept between us will not achieve anything. Share it with the community = creativity and research. Shared is how it should be. The SDK will basically allow the community to reverse and open doors towards homebrew applications being present on the Xbox One."
"Once the SDK is out, people who have knowledge or has in the past reversed files related to the Windows (8) operating system should definitely have a go at reversing some files in there," the group added. "Why? Well, the Xbox One is practically a stripped Windows 8 device and has introduced a new package format that hasn't had much attention. This format is responsible for updating the console and storing applications (Games are under the category of 'Applications' on the Xbox One) and is a modification of Virtual Hard Disks."
