Hello! I purchased a physical copy of Destiny when it was first released, and when The Taken King was due to be purchased I could not afford any of the bundles that included a digital copy of the base Destiny game; my question is, is there any way to buy or upgrade the base non-Taken King Destiny without having to buy either of the two rather expensive bundles that include all the content I already paid for? The store page for the stand alone Taken King expansion mentions Destiny being available separately, but I am unable to find any such product. Thanks in advance. EDIT: I forgot to clarify that I not looking to upgrade from last- to next gen versions, but to purchase the base Destiny game so that I won't have to use the disc I already own. I very much appreciate the quick responses, and I apologies for the confusion.
