Totally new Xbox Live experience- Microsoft hints

Xbox live imageMake no mistake, we've seen curious job postings lead to changes in our favorite gizmos before, and hopefully, a recent ad on Microsoft's website is no different. A listing seeking a Program Manager explicitly states that it's looking for someone to "be involved in the next release of Xbox," and wants that very individual to be "part of the Xbox Live team that's responsible for creating a completely new way for mainstream audiences to enjoy the Xbox and Live."

Better still, the description suggests that the team would be "building the games, the console interface and logic, and the server support for a totally new Live experience." Granted, there's nothing more to go on than this at the moment, but we can't help but be a teensy bit excited about the notion of an overhauled Xbox Live.
