The upcoming issue of PC Gamer has an interesting concept design for a Games for Windows display that clearly shows multiple Gears of War PC boxes (page 28 of their Holiday Issue). Is this a nudge and a wink of what's to come? Given the similarity of design architecture between Xbox 360 and Windows gaming, it's a no-brainer that Microsoft would seek to put its successful gunslinger Gears of War on every platform it has available.
It would be a good moneymaker and (if Halo 2 is any indication) another incentive for gamers to upgrade to Windows Vista. However, IGN has been told by Microsoft that there no plans to announce a Gears of War PC version in the near future.
