Peter Rojas at our sister publication has some details on XNA:
It's mainly meant as a way for publishers to build new video games more quickly, but XNA, Microsoft's new set of developer tools for Xbox 2 and PC games, will also have the nice side-effect of making it possible for owners of an Xbox 2 console to plug their controllers into the back of a PC and use it with PC games. There's also talk of extending the Xbox Live service so that PC and Xbox gamers can play head-to-head against each other. More from CNN.
