I know the delays are for a good reason but it get discouraging not only for this launch but to hear that there will be a delay of about two years for the next flight. That's the difference between the Saturn V and the SLS.

The two years (22 months) between EM-1 and EM-2 is primary driven by the time needed to modify the mobile launcher to support the taller Exploration Upper Stage (EUS) equipped Space Launch System that will launch on EM-2 for the first time.

Officially, NASA is targeting December 2019 for EM-1:
While the review of the possible manufacturing and production schedule risks indicate a launch date of June 2020, the agency is managing to December 2019," said acting NASA Administrator Robert Lightfoot. "Since several of the key risks identified have not been actually realized, we are able to put in place mitigation strategies for those risks to protect the December 2019 date."
