I really hope they don't push the new profiles out tommorow, particularly since the new profiles still do not work with IE7. Once you go to try the profile, facebook comes back with an error saying that the browser is outdated and needs to be upgraded to the current version. IE 7 is the current version.
It's the same problem we had when facebook rolled out their integrated chat feature that didn't work under IE7 for a good month or more.
