Reader Simon wrote in to us this weekend to let us know that he'd received an e-mail, one targeted at "subscribers to the MS download email service", that listed Halo 3 as one of the downloadable demos that take advantage of DirectX. Does that mean that Halo 3 is confirmed for a Games For Windows release? Not so fast, pal. Sure, it's entirely possible, given that Halo and Halo 2 both made the Xbox 360 to PC jump about two years after their respective console releases. And, sure, games like Gears of War have been inadvertently "announced " for the Windows platform in marketing materials, but you're really jumping to conclusions here. You think Microsoft is going to let something like this leak? After all, only about 98.44% of Microsoft-based rumors are true. We're following up with the company to get our sweet taste of carefully worded denial right now.
