In upcoming Gnome (3.8) we will see 4 new Apps -Videos(?), Photos, Music, Calendar. However there are some more interdependent Apps on the table..

Potential Applications

Description: Some applications that would be nice to have, but aren’t necessary for a reasonable core user experience. These aren’t planned for 3.8 yet, and they might not arrive.

1. Backup

Description: A tool that allows someone to backup and restore their data and settings. Backup hasn’t been designed yet.
