Redesigns for both Orgrimmar and Stormwind are on the table if World of Warcraft: Midnight's Silvermoon overhaul is well received
World of Warcraft: Midnight, the incoming expansion for the two-decade-plus MMO, will be taking players back to Silvermoon—that's been known for some time, but it's also a bit of a continued experiment. See, WoW's a wizened beast with expansions in the double digits to its name, and if you keep slapping continents on the old girl, it's going to stop feeling like a World of Warcraft and more like a hodgepodge...er, of Warcraft.
Anyway, we know that we're going to get a redesigned Northrend again for the next next expansion...
