MTV's Multiplayer speculated and has now confirmed that Microsoft is currently hiring new team members for Peter Jackson's mysterious Halo-related project. The speculation arose when Microsoft posted several new job listings looking for people to "help develop a new experience in the Halo universe" alongside an "external luminary." So, Halo and a luminary. Sounds like Peter's project to us.
While at first it seemed strange that Microsoft would only now be hiring for the project, Microsoft followed up with MTV to clear things up. The company told MTV, "Microsoft Game Studios has been hard at work collaborating with Peter Jackson and Bungie on the development of [a Peter Jackson-helmed Halo project]. At this time, it's necessary to grow the internal team to keep pace with development. Bungie will continue to remain involved in multiple aspects of the Halo Universe with MGS." So, it turns out that the project's development team is merely expanding -- as opposed to just now being formed -- which would indicate the project has become more expansive as well.
Let's hope we can hear some news about the actual game sometime soon. Seriously, we're starving for info.
