Though 2K Games' middle-of-the-night XCOM announcement listed California-based 2K Marin as the studio heading up development of the title, 1UP reports that 2K Marin's "Canberra, Australia arm" (read: 2K Australia) will be in charge of the project. For those of you playing along at home, 2K Australia was the Australian counterpart to BioShock developer Irrational Games before the studio split to work with 2K Marin on BioShock 2, while Kenny L and company got to work on a separate (still unannounced) project.

That said, this news frees up 2K Marin's core team for other projects. And if we were betting men, we'd put our money on the California arm of the company working on a third entry in the BioShock series. When reached for comment, a 2K Games rep told us we'll hear more specifics about XCOM and 2K Marin "over the next couple of months."
