Check your email, you probably just got a notice from Microsoft inviting you to a site demonstrating the new Xbox Live experience. No, a release date is not specified. The site features examples of the content and features you can expect once it does arrive, presented in a simulation of the new dashboard. There are videos on avatar creation and interaction with your friends (some of which we've already seen), and another touting its online entertainment capabilities. Everything has the bigger-better-more company shine on it. The addition of the Inside Xbox channel looks intriguing, but few specifics beyond the teasers offered.
