ZeniMax creative director Paul Sage told IGN that Elder Scrolls Online's endgame-focused Craglorn update is coming this week. "I think we're still at the tail-end of six weeks[.] I could be wrong there[;] it's all a blur," Sage said. "But we're either in the sixth week or the seventh with this update[,] and I believe our next update is fairly on schedule," he said. After it launches Craglorn, ZeniMax plans to unveil the Crypt of Hearts veteran dungeon. IGN also says that it talked to Sage about player housing, the Thieves Guild, and the Dark Brotherhood, but that information won't be available until later in the week.
[Update: ZeniMax has just posted that in fact the Craglorn update will arrive tomorrow: "We are very happy to announce that Update 1, including Craglorn, will hit the live servers starting tomorrow, when we'll be bringing the servers offline to begin deploying Update 1. [...] Offline maintenance will begin on Thursday, May 22 (tomorrow!) at 8 AM EDT for the North American megaserver and at 10 PM EDT for the European Megaserver. Craglorn and the rest of Update 1 will be available to players after the end of the maintenance period."]
