It would be nice, I'd like to think the reason why they've been so secretive aside from Raid 8/24man and Sanctuary is because revealing any other artwork/name for future content would completely spoil the direction of the story. AKA we don't have the name of the Relic location yet, potential Deep Dungeon or even the potential DOL/DOH restoration content. Those 3 things have a very high chance of being tied to spoilers so it will be interesting to see what the next LL reveals about the 6.1 patch cycle.
