points out a job posting for a Lionhead/Microsoft Game Studios Network Programmer
that seemed to have indicated there are plans to bring Fable III
to the PC and to provide cross-platform gameplay with the Xbox 360 edition of Lionhead's action/RPG sequel. That's in the past tense because the listing no longer contains the clues they noticed, but apparently at one point the listing indicated the job: "involves converting and maintaining the network code of the Xbox 360 version of this game to the PC, and enabling the Xbox 360 version and the PC version to play together."
