Surprisingly, it has been discovered that there is a section on Steam for Xbox support.

Does this mean Steam will be appearing on Xbox 360 in the future? Probably. However, it might just be a section for existing Xbox 360 titles on Valve’s platform. Currently, there is still no Steam version for the Xbox 360 since Microsoft is still not opening up their doors to Xbox Live. As of now, Steam is only available PS3 home console.

It would be cool for Xbox 360 owners if this actually goes through.
