People might have thought Fable 3 was the start of a new era for Microsoft games on PC. People then might have been disappointed that nothing was said about any other PC games at E3 (though to be fair barely anything was said about new 360 games at E3).
Well, according to an internal Q&A at Microsoft, more PC support IS coming.

Quote from MS:
In terms of revenue, Windows is far and away the largest gaming platform in the world, so it's an incredibly important part of Microsoft's business. From core games like "Fable III" to casual, social and Facebook titles, more gaming happens on Windows than anywhere else. Windows 7 is a world-class gaming platform, and you can bet Microsoft has a vested interest in using it as a platform for amazing first party content. "Fable III" on Windows as well as Xbox 360 this holiday is a great first step, and we'll have more news for you later this summer.
