There is one stormcaller subclass pair of gauntlets revealed already, but there could be another one, look at this. https://www.youtube.com/watch?v=ROHqE9NuaWk Look at that warlock walking in the backround? He has blue sunbreakers. Why this could happen: 1. Each warlock subclass has one pair of gauntlets with the corresponding element flowing in it. 2. Next subclass is arc, so arc gauntlets? 3. http://imgur.com/dWS9ma2 look at that, the final vanilla cutscene. See the warlock standing at the front? He's wearing the nothing manacles. 4. If he was wearing a HoW item before even TDB, that means it's possible for another warlock to be wearing a TTK item before TTK. 5. https://www.youtube.com/watch?v=oh1F46KoPAc skip to 2:02, the weapon that he takes from the guard? Vestian Dynasty. 6. Look at Lord Shaxx's weapon stock behind him; Lord of Wolves is there. 7. First cutscene. The three fallen can each be seen holding one of the three elder cipher weapons. 8. If future gear and weapons are seen in the cutscenes already, then that means that the warlock gauntlets seen in the first tower cutscene could be coming up in TTK.
