Blizzard’s considering it.
Blizzard would like to make World of Warcraft expansion packs more quickly, and is considering making smaller expansions in order to release them more often, designers Greg Street and Dave Kosak have revealed.
Blizzard has so far released an expansion pack every two years, but an 18-month schedule is “certainly a goal, we would like to get expansions out very quickly because we know players respond to them very well,” lead systems designer Street told Eurogamer in an interview marking the launch of third expansion Cataclysm.
Earlier in the game’s life, Blizzard said it aimed to publish an expansion every year, but “we’re not anywhere close to that now,” Street admitted.
