While there's a lot of info, the most interesting bits concern the projected live date of the long-awaited House of Crom dungeon. Morrison says that the new content will most likely debut on January 11th or 12th, and that the dungeon will be playable on AoC's test shard over the Christmas holidays.
Also new this month is a detailed explanation of the game's upcoming open-world PvP content. When the new feature was first announced, the game's hardcore PvP community unleashed an epic tidal wave of tears due to suppositions about "PVE sheep trying to pass in PVP wolf's clothing," not to mention concerns about a possible rehash of the game's disastrous Shrines of Bori mechanic. Morrison spends several paragraphs of this month's update explaining what Funcom has learned since Bori, and how that knowledge is going to translate into a fun system that isn't exploitable via PvE mechanics. You can read the full update at the official AoC website.
