The seventh Vault of Glass chest, which was added in with the Age of Triumph content drop, has been discovered in the Trials of Kabr! Edit 4: Fixed original description to better match the circumstances of the find, including that the chest was found after being added in by Bungie. Edit 5: Guardians! Please keep in mind that I (as do many others) count the chest from the hidden mission within Paradox as one of the seven chests. If you do not view this chest as one of the many, then consider this final chest to be the 6/6. Edit 6: Though I remain a skeptic, I do find the theory that this chest is simply a teaser at the real final chest to be intriguing. If anyone finds any evidence come Tuesday next week, please make a post on here! I'll be doing my own spelunking, but we'll just have to wish and hope!
