IGN then gave Kotaku the nod, who went to work checking into some of the stuff Beantown Games posted. The blog found inconsistencies in the Beantown post, with the supposed leaked press release being a near carbon copy of the original press release for Gears of War 2 on Xbox 360. Then, there's the UPC codes, which apparently all point to The Golden Compass. It's odd, to say the least.
As much as all of this seems like malarkey, one shouldn't entirely rule out the possibility of Gears of War 2 on the PC. The first game released on PC in November of 2007, a full year after the release of the original Xbox 360 game. Since the sequel released on Xbox 360 in November of last year, we wouldn't put it past Epic and Microsoft to crank the game out on PC some time in 2009. Though, when we contacted Microsoft, a spokesperson said "We have no plans for Gears of War 2 on the PC," so take it as you will.
