Seems we won't be seeing Gears of War on Windows any time soon, check out GamerScoreBlog for what appears to be the official line from Microsoft.

Thanks Voodoo Extreme

Here's the truth:

* Yes, Microsoft provided the image that is published in the Games for Windows cover story in the Holiday issue of PC Gamer magazine.
* Yes, this image contains what looks to be box shots of Gears of War with the Games for Windows branding bar on the box art.
* NO, this is not a confirmation, leak, tease, or sly viral attempt to announce, confirm, or admit that Gears of War will be published for Windows.

Here's what happened: These images were created using draft templates for the Games for Windows box art and a variety of Microsoft Game Studios cover images. Gears of War was accidentally included by the artist as one of the MGS titles used as examples to show what our retail setup would look like. This DOES NOT indicate a confirmation that Gears of Wars will be a Games for Windows title -- it was a concept image created by a concept artist, nothing more.

The final bit of the post doesn't actually say it's never going to happen though, just obviously not yet.

We're incredibly excited about the success of Gears of War on Xbox 360, but we have nothing further to announce about Gears of War, or any other platforms it might come to, at this time.
