While distributions like Fedora and openSUSE have switched from Upstart to systemd, Ubuntu is going to remain loyal to its six-year-old-replacement to SysVInit. There's been no indications that Ubuntu Linux would migrate to systemd, and after some technical sessions this week in Oakland, Ubuntu will continue to be cemented to Upstart.
One of the sessions this week at UDS-Q was about "Upstart Service Readiness" with the notes being available here while a second session focused upon a roadmap for Upstart. The notes are available here.
Among the future ideas mentioned for Upstart are interactive boot, Upstart and SysV segregation, event log for problem determination, enabling user jobs, user-job logging, custom actions, Upstart as a cron replacement, and mountall plans.
