Those of you in the NXE preview program--and as of yesterday, that's a lot of you--have probably noticed that up till now, Xbox.com hasn't supported some of the new features being introduced in the dashboard update. Mainly, the gamer pictures for NXE users have been displaying as big fat question marks when those users apply an avatar snapshot as their pic, and no other sign of custom avatars has been spotted around Xbox.com profile pages.
After a little bit of downtime and a little maintenance, the site is back up and running and now supports all those snazzy custom avatar features you've been oh so excited about. See below for an example of what your avatar will look like on your profile page. As dumb as I thought avatars were initially, I have to disclose the amount of time I sat there trying on stupid virtual outfits for my dude. It was a long time.
Don't forget: If you haven't gotten into the NXE yet, you and everyone else will be downloading it tomorrow when you power on your console.
UPDATE: videogaming247 points out that the new web-based Xbox Live Marketplace is online--kind of. It's just a big Coming Soon graphic at the moment.
UPDATE 2: I can confirm that there are currently no acceptable sets of sideburns available for use on avatars. Come on, who has muttonchops in this day and age?
