There's a Halo article on PC Zone that says "Despite all the rumours, Halo will come to the PC, complete with online multiplay," saying "PC ZONE can now confirm Halo will indeed be a PC release, though exact release dates remain uncertain, and it is sure to be at least a couple of months after the US Xbox launch." Since they don't offer any source for this 'confirmation,' I guess we file this under the 'in spite of all the rumors, here's another rumor' category. Of course, regardless of their acquisition by Microsoft, Bungie has never once wavered from their stance that Halo is ultimately destined for the PC and Mac in addition to the Xbox, so this article is really just repeating the party line.
