Blizzard just trademarked "The Dark Below"

Blizzard just trademarked 'The Dark Below'
It's been discovered by multiple sources that Blizzard recently trademarked the term "The Dark Below" to indicate, amongst other things, a computer game.

Is this the new Warcraft expansion? Or the Diablo 3 expansion? Or something else entirely. We have zero idea of what this actually is, but hey -- that doesn't mean it's not something to look at and speculate on. It is interesting that "The Dark Below" exists in WoW via Blizzard's non-canonical RPG manuals and via a brief mention with Ozumat.

So start your engines ... something is happening.
