Obsidian Entertainment Mystery Project Countdown Continues

The countdown for the mysterious "Project X" from Obsidian Entertainment has gone from 4 to 3, which suggests that a potential announcement will come on Friday. There is some text on the page and in the sourcecode, which reads:
The book unread is unwritten. The reason we don't explain it is the reason we use it. Its power is in its mystery. That is the Leaden Key, in part, in whole. Is it clear?
Digging for truth buries the seeker.

--. X . X X . T X --
-- Two centuries ago, your divine champion told the people of Dyrwood to grovel at his feet. If you've come on pilgrimage to the blasted crater that was our reply, Godhammer Citadel is *that* way. --
I don't think it's clear at all! But it sounds like Godhammer Citadel got blasted to smithereens by the people of Dyrwood, and that digging for the truth is a bad idea. The "X" bit initially read --. X . X X . X X --, so it seems like it is slowly revealing something.

And with that, a new speculation thread is spawned.
