Ex-BioShock Staff Starting New 2K Studio?

Shacknews is reporting that a recently edited Gamasutra job listing called for a lead animator to work at a new 2K studio started by "some of the creators of the award-winning Bioshock."
According to a Gamasutra job posting that now appears to have been slightly changed, members of the BioShock development are forming the core of a new game studio in the San Francisco Bay Area, probably at 2K's new headquarters in Novato, California. The company is calling for a lead animator with no less than eight years of experience.

Though the phrase is no longer part of the listing, Google caching reveals the sentence, "Some of the creators of the award-winning 'Bioshock' are starting up a new studio in the Bay Area and are looking for a Lead Animator." BioShock was developed by 2K Boston and 2K Australia, formerly collectively known as Irrational Games.
