For about a month now we have known the Whispers of the Old Gods is Hearthstone‘s newest expansion but Blizzard had been reluctant to announce a date. They have finally come out and said that it will be released on April 26th, a week away. There had been a lot of speculation that this would be the date of release based on a bug in the in game store and it appears to be the case. This is the longest Hearthstone has gone without an expansion and with over 70 of the 134 new cards revealed so far I think that things will be shaken up.
The other question with this news is when Standard and Wild Format will commence. These formats separate the card pool based on when the cards were released. Wild ladder allows all cards, while Standard only allows for the classic set as well as cards released in the previous year. Reason dictates it would begin on May 1st as that is the start of the new season, but that’s only speculation at this point. You can still pre-order 50 packs for an exclusive card back up until April 26th.
