Hearthstone: Whispers Of The Old Gods Now Available For Pre-Purchase, Earn Nine More Deck Slots

As of today's patch, Hearthstone players can now pre-purchase Whispers of the Old Gods' 50 booster packs for $49.99 bundle. They will not be able to open any of the packs until the expansion releases sometime before May 31st. However, they will be able to access their exclusive card back upon purchase.

The way that deck slots are unlocked has seen some changes. New players will "unlock a Basic class slot for each hero they've unlocked." Once all nine have been unlocked, they will earn nine extra deck slots—one Basic deck per class. All existing players who have all nine heroes unlocked will receive nine deck slots.
