Our old friend RaptoR at Planet Gears of War puts forth a handful of zany predictions about Gears of War 2. Here's number 4:
4. There will be a PC release within twelve months.
PC gaming isn't dead yet, despite the army of angry Internet people who might claim otherwise. The PC version of Gears didn't sell huge numbers, probably due to the horribleness of Games for Windows Live and the fact that everyone has already played it on the 360. Gears PC also suffered from immense competition when it was released in November 2007, not least of which was Epic's own Unreal Tournament 3.
Nevertheless, we predict a Holiday 2009 release for Gears of War 2 on the PC. It takes relatively little effort to port an Unreal Engine 3 game back to Windows, and Epic has the time and manpower to pull it off. The only question is whether it'll be received any better than the Windows version of the first Gears of War.
