Blizzard has let loose the date of their first expansion pack for Diablo III as Reaper of Souls will be released on March 25th, 2014. The expansion pack will see you take on the Angel of Death.
The cost of the expansion will be $39.99, not quite full game price but close.
I'm pretty excited about it though as there are some great features coming and there will also be the removal of the auction house so you guys have a few months to get your auctions settled before it's all gone. It's a good thing Blizzard is making it easier to get quality items in the expansion pack.
Reaper of Souls will be available for both PC and Mac on launch day.
