"Halo 4: I Get a Woman!" - Sgt. Mjr. A.J. Johnson, RIP

[Kornman00]

Microsoft owns Halo, they would never let anybody put it on any other platform than their other baby, the Xbox.

With Bungie going to other platforms, and so many other games being multiplatform, and W8 coming out...I don't think this is the case anymore. So a PC release for H4 is likely I think.
