Sometimes we come across rumors that are kind of no-brainers, things you know are pretty damned likely, such as this one from Joystiq claiming that the next version of the Xbox, due a few years out, will allow you to keep your XBL gamer tag, achievements, and other personalized content when you upgrade.

Microsoft would be foolish not to do this, as the stuff is all XML based and it would be very easy to port the stats.

The really juicy part says that MS has already started talking to developers about keeping this idea in mind for next-gen games, because even if MS offers the service, it’s up to the developers to implement it. Very cool.
