It seems that Microsoft can't put down the Halo franchise, but then again, who would want to? Gamasutra.com has a job advertisement posted by Microsoft that indicates that there is another Halo project in the works in addition to Halo 3: ODST.

"Microsoft Game Studios' Halo team is looking for exceptional art talent to contribute to a new experience in the Halo universe. Teamwork, innovation, attention-to-detail and unbridled passion are characteristics we look for in all of our artists." As far as new experience is concerned, could it be possible that they are referring to a mobile type project we reported in April? It's hard to tell if this posting is for an entirely new Halo experience branching off of Halo 3, or if it is something else entirely.

We've been surprised before, but Microsoft likely won't be announcing this project anytime soon as we gear up for the hype of Halo 3: ODST at this year's E3. The release date of Halo 3: ODST is still unknown, but will be coming out later this year.
