To expand on what Dan mentioned earlier, Fantasy Flight Games has officially announced Rune Age. Follow the link the their full announcement.

And yes, it's yet another deck building game, the 5th game to use the Terrinoth setting begun in Descent. The description promises a faction-specific set of cards for each player as well as scenarios with different victory conditions to set it apart from the 75 other deck building games that have been released since Dominion swallowed the gaming universe.

I will try and keep my inherent cynicism at bay while we wait for more info to develop. Who am I kidding, it's FFG, I'll buy it.

While nothing official has been announced by Fantasy Flight some participants at the recent Realms of Terrinoth event got to play a game in development by FFG called Rune Age.

This looks to be another in the growing stable of deck building games. You can find the post here and it does a great job of explaining the game.
