A picture of a white Xbox One development kit has been leaked to Reddit.

As spotted by Neowin, the unit in question is based around the same form factor and overall design of the console first revealed by Microsoft in May, and offers a peek at what a different colour retail model could look like in the future.

Apparently, the white dev kit is not the most recent version Microsoft has provided to game studios.

A developer reportedly confirmed to be working on an Xbox One game said on Reddit: "The zebra ones were also earlier devkits. We've gone though several revisions since the original alpha kit (giant server case) and the current one we have looks like the launch version."
