IGN did an interview with Cliff Bleszinski, design director for Gears of War and Gears of War 2, where he revealed that Gears of War 2 will not come to the PC:

“Gears of War is a great franchise first and foremost for Xbox 360, and therefore we’re focusing on that platform for Gears of War 2. We’ve decided we’re not going to do a PC version this time around.”

Here you go – another good reason to eventually buy the Xbox 360 if you haven’t already (I haven’t…).
