<a href="http://www.mmo-champion.com/content/3339-Blizzard-Trademarks-The-Dark-Below-WoW-or-D3-Expansion">News today</a> that Blizzard has just filed a copyright for the title, "The Dark Below" for a computer game. There's some "maybe it's D3 Expansion!!?1!" theorizing, but the term seems clearly <a href="http://www.wowwiki.com/Dark_Below">tied to the Warcraft</a> world. <blockquote>The Dark Below is a place inhabited by demons, devils and infernal creatures, from where some sorcerers take their power directly and sometimes have a patron beast to foster their magic.</blockquote> I'm not a WoW player, and it would be an odd Blizzard expansion title as it's not <a href="http://diablo.incgamers.com/blog/comments/diablo-3-expansion-titles">3-4 words with an "of" in the middle</a>, but the lore info seems promising. I'd rather head to hell than to Pandaland any day. Since new trademarks and copyrights have to be publicly listed (that's the whole point) fans have caught advance word of upcoming Blizzard titles in the past. <a href="http://diablo.incgamers.com/blog/comments/blizzard-trademarks-cataclysm-new-game-or-just-wow">Cataclysm, for instance</a>. The filings can be obscured a bit by being filed through different company names, and that might be what Blizzard has done with whatever they're going to call D3X, since we've not seen any likely leaks of likely titles for that, yet. Note that Diablo Salvation is a dead filing that Blizzard never publicly commented on, from back in 2002.
