Major Nelson has today revealed that xbox.com will get a facelift. You can see a preview of the change via his flickr account.

Both xbox.com and the forums will be down for a short period of time while the update takes place.

A highlight of the changes are as follows:

• Browser based Avatar editor: Edit your avatar and preview avatar items before purchase
• Combined views for messages, friend and game requests
• Improved notification of your account subscription
• Leverage Family Reports to understand what your family is doing and how they are using LIVE
• Play web games with your Xbox LIVE friends on the web or on Windows Phone 7
• Marketplace: More powerful search and more intuitive ways to browse and filter

Initial opinion is that it looks a lot cleaner and fresher than the old design and a lot easier on the eye.  The ability to edit your avatar online looks good.
