New Facebook Layout Announced on 60 Minutes Is Not Showing

So the new Facebook layout that was announced on 60 minutes tonight is not showing yet on my computer. What’s going on with that? From my understanding, some people got the new layout as early as noon today, but it’s now 9:30pm and I’m still not seeing the new Facebook layout. Is anyone else having this problem? Is there any way to fix this, or do we just have to wait for Facebook to get to our accounts?
