Luke said recently (in the December 2017 EDGE article) that there are big hints in that post-credit scene -- specifically that although the payoff of the black pyramids being awakened won't be paid off for years, the fact that Mercury was the first area to be shown as being impacted by the Traveler's light expansion was a very intentional setup of the first expansion. Mercury = Osiris, and very likely includes more about the Exo Stranger, Mara Sov and/or Prince Uldren.

Please, pretty pretty please Bungie, let this be true.
