After a few months out, today Wizards of the Coast announced the first expansion for Duels of the Planeswalkers 2012. The expansion will officially unveil Innistrad cards, allow you to now play as the Archenemy in the game, as well as add more campaigns and opponents to face. See the full list of new features and functionality below.

• Three new playable decks: Liliana Vess's "Grave Whispers" deck, Ajani Goldmane's "Auramancer" deck, and Ral Zarek's "Cloudburst" deck
• Six exclusive sneak-preview cards from the upcoming Innistrad expansion
• Players can become the Archenemy in single-player and online multiplayer formats
• Six new single-player campaign levels and eleven Archenemy single-player campaign levels
• Four Archenemy challenges
• Four additional card unlocks for all thirteen Duels 2012 decks
• New achievements on Xbox, Steam, and PlayStation
• New loading screens featuring art and text exclusive to the Duels 2012 Expansion

The six cards are most likely the ones previously spoiled unofficially by posters on MTGSalvation. And this is the first confirmation of Ral Zarek entering the fray after he was discovered hidden within the game, though not included in its original release.

This expansion is scheduled to released on Sept. 14th, but for those attending PAX you'll be able to see the game at the Wizards booth before the game releases.

Official announcement.
