It's simple, I already have an Xbox One but have never been able to justify buying another copy of The Taken King (DCE) which is on my 360. Solution: for those who bought TTK on last-gen [u]at full price[/u] should be able to freely download the current-gen TTK DLC, before or within the release day of Rise of Iron. Especially for those who want the pre-order of the new black Gally.
