Games for Windows Live now free

Interesting that this didn't get announced at E3, but Games for Windows Live is now free for all. Yep, totally free, cross-platform multiplayer with the 360 included -- which obviously raises the question of whether Live will ever be free on Xbox. We think that's a pretty safe no -- unlike Games For Windows, Xbox Live actually makes money, which is pretty hard to turn down, and without a ton of competitive pressure from, say, Playstation Home, it's hard to see why Microsoft would turn that funtime cash fountain off. Still, there's always hoping, right?
