The rumor of an Xbox One/Sunset Overdrive bundle has been floating around for quite some time now. Just recently, a French site known as Micromania has leaked a white Xbox One, that would apparently be bundling with Sunset Overdrive. The now-taken down listing priced the bundle at €399. This bundle makes sense, since a white PS4/Destiny bundle was just recently announced. The site has previously leaked unannounced games, such as the Titanfall Beta.
Update[]
An official Xbox One bundle has been announced.
