Facebook has announced the release of the profile sandbox for developers. If you have added the developer application, this means that you can now check out what your new profile is going to look like. You can view the profile at www.new.facebook.com/profile.php. Facebook has also provided a new developer library and a sample application that developers can check out to see how all the new integration points work.
The launch of the profile sandbox means that developers now have at least two weeks to get their new profiles out. Most likely it will take Facebook longer then two weeks to get everything rolled out. Facebook has also said that the new profile design could change as it is still in beta. Read more about the changes over at Facebook. I was able to access the new profile and came up with the following screenshot:
