Diablo 3: Reaper of Souls is currently in closed beta, and though its limited to a few gamers under the "family and friends" remit at the moment, Blizzard intends to expand the beta to encompass a wider swath of their audience before the year's end.
Writing on a post on the Battle.net forums, community manager Lylirra wrote, “In the past, participants in this particular phase of public testing usually only include friends and relatives of Blizzard employees.
“With Reaper of Souls, however, we’ve decided to buck that trend and extend invites to valued media contacts and key members of the Blizzard community.
"We’re also inviting 3,000 of our most active Diablo III players from around the world who’ve opted in for beta testing—something we’ve never done for any Friends and Family Beta test before!”
The closed beta will offer the full expansion sans some of the content reserved for the release version of the game.
