Not sure if this has been posted somewhere else, but I just noticed Paizo has their 2014 - 2015 catalogue up online, and it contains a detailed description of Wrath of the Righteous. Spoilers: everything about it sounds awesome.

PATHFINDER ADVENTURE CARD GAME: WRATH OF THE RIGHTEOUS
THE ABYSS AWAITS!
When the city of Kenabres is destroyed by a horde of demons, only you can save the world! In Wrath of the Righteous, the epic new Adventure Path for the Pathfinder Adventure Card Game, you will travel to the Abyss to battle the malevolent minions of the demon lord Deskari. Along the way, you’ll become mythic heroes that rival the greatest legends the world of Golarion has ever known. The saga begins in the Pathfinder Adventure Card Game: Wrath of the Righteous Base Set. This cooperative strategy card game lets 1 to 4 players enter the hellish Worldwound. You can choose from 7 characters, each with a different style of play. You’ll build a deck of powerful boons, which will grow according to your desires over a six month campaign. You’ll gain a new set of cards called companions, which can support your characters in play. Over time, you’ll gain a mythic card, which will allow you to warp the rules of the game and use the first ever 20-sided die to appear in a Pathfinder Adventure Card Game release.
The Pathfinder Adventure Card Game: Wrath of the Righteous Base Set contains:
• More than 500 cards featuring a new set of boons for your characters to collect, and never before seen monsters and barriers of a decidedly abyssal nature.
• 7 character classes, including the all-new arcanist, cavalier, slayer, and summoner.
• The Worldwound Incursion Adventure Deck, a 110-card deck that begins the Wrath of the Righteous Adventure Path.
• A complete set of 6 polyhedral dice, including the first d20 in Pathfinder Adventure Card Game.
This set can be supplemented with the Wrath of the Righteous Character Add-On Deck, featuring 4 more characters, including the first appearances of the bloodrager, hunter, and shaman. Adventure decks release monthly starting with March’s Sword of Valor Adventure Deck.
