The status of Nostalrius, the fan maintained Vanilla WoW server has been a point of contention between Blizzard and fans. Especially so after Blizzard shut the server down at the beginning of this year. In a show of good faith the Blizzard development team met with the founders of the server.
Since, Blizzard has not provided any plans to come forth with a server of their own. A move that would likely be successful given the success of legacy servers in other games, such as Runescape. Blizzard has stated that "They [Legacy Servers] are something we're taking seriously". Yesterday, following a disappointing silence on the matter from the publisher at Blizzcon, Nostalrius announced their plans to revive the server, calling for a "Legacy community reunification."
The plan is to release the Nostalrius source code to another existing Vanilla server, Elysium, and effectively combine the two communities. The idea being that a unified community might force Blizzard's hand.
We'd love to see Blizzard embrace the Legacy community, but until that time best of luck to those fighting the good fight.
