Rise of Tiamat has been delayed a couple of weeks. Hot on the heels of the delayed release dates of the Dungeon Master's Guide, and the D&D Spell Cards from Gale Force 9, WotC has just announced that the Rise of Tiamat, the sequel to Hoard of the Dragon Queen, and the second - and concluding - part of the Tyranny of Dragons storyline for D&D 5th Edition (7 brands in one sentence!) has been delayed 2 weeks from October 21st to November 4th, 2014. Preferred stores will have it on October 24th. WotC says "The test print run didn’t match our quality expectations and even though addressing these issues has caused a delay we must put out the highest quality products we can."
