According to A Talk with Jeff Strain, a Blizzard veteran who founded ArenaNet and was NCsoft's President of Product Development before leaving, he has founded a new studio called Undead Labs and is planning a brand new title about zombies. The zombie-based MMO will be a console MMORPG.
"You look at the name Undead Labs. There's a reason that is unique," he explains. "I'm very specifically setting out to make the best zombie MMO ever. This is what my company does and I wanted the aim of the company to reflect that and I wanted the people that work with me to share that passion for zombies and console games. Another part of it is that I don't intend to be a 300 or 400 person office. I think there are smarter ways to develop MMOs and my goal is to have a studio that can stay nice and small, but still really deliver content at that AAA level... the biggest thing for me -- when a team gets that big -- is the loss of culture, and the loss of identity. I would really like to build a studio that can maintain its spirit over time. It's going to take some very different thinking about production."
Anyhow, I confidently expects to the game.
