Was there ever a leaked build of WP 8.0 for Lumia 1080 that had the notification cent

Was there ever a leaked build of Windows Phone 8.0 for Lumia 1080 that had the notification centre? That's 8.0 not 8.1.

My Google-fu isn't good enough to get a definite answer on this. I think I saw pictures of some hyrbid builds before 8.1 was out.
