The game we have all be waiting for will soon be coming to the Xbox One via the backwards compatibility feature, the game I'm referring to of course is none other than Call of Duty: Black Ops.
How do I know this? Well simple Amigos, a DLC listing on the Spanish Xbox Store has let the cat out of the bag.
What you don't believe me? Well here is how to check for yourself, simply switch your language and region to Spain 'Espana' on Xbox One, now find the listing for Call of Duty Black Ops' third downloadable map pack, Annihilation, on the Xbox Store.
If you can't be arsed to change the language and region on your own Xbox One, then just check out the image on this article and you will clearly see that it shows Annihilation map pack for Black ops on the Xbox One. You can not actually download it right now though.
