Gjallarhorn is definitely coming back. You know how I know? I know because Bungie knows that the player base will pay to get it back. We've been repurchasing the same armors and weapons time and time again for years now, showing Bungie that they only need to take an item away from us and dangle it on a stick in front of us and we'll gladly pay for it, yet again. With Bungie pushing the f2p microtransaction economy more and more, it's not a matter of if they bring back Gjally, but how much they'll charge when they do.
