The website of Xbox Live (Xbox.com) will be relaunched in a few hours from now with a bunch of new features, which will include an avatar editor (much like the Miis in Nintendo Wii, only less silly-looking), a new message viewer, and an updated Marketplace browser.
But what makes the relaunch more exciting is that members can now play Web-based games with their Xbox Live friends whether on the web or using a Windows Phone 7 device.
Just take note that all while Xbox.com is down today for the facelift and in subsequent days for maintenance, the Xbox Live service remains uninterrupted.
