Blizzard appears to be working on a fifth title according to two new job postings.
The fifth brand-new unannounced game surfaced last week following previous hints that Blizzard was interested in working on a completely new IP.
Currently Blizzard is working on Starcraft II, Diablo III, a new World of Warcraft expansion, a next-gen MMO, and a new unannounced game that may be a new IP. Blizzard hinted at developing a game based on a new IP back in 2006 when Blizzard COO Paul Sams commented: "I wouldn’t be surprised to see a new franchise from us at some time in the future; there’s certainly a desire to do so."
Blizzard is recruiting again and have been looking for programmers on programming job site forums where two new positions have been advertised by Blizzard's 'Slouken' who has been working on World of Warcraft, specifically with the UI and interface community.
The positions have been advertised stating:
"Blizzard Entertainment is seeking an experienced gameplay engineer to focus on game rules systems for an unannounced title. This is your chance to get in on the ground floor of a dynamic and focused team working on a brand new project. Blizzard Entertainment offers a fun, creative, and technically challenging environment with excellent compensation and a full range of benefits."
Based on these two new job postings for software engineers, we can assume that a new IP from Blizzard is in the works.
