I would like to get dotted line for expected end date for event.Please check the following attachment.
we should not extend the red dotted line and we can able extend the normal event.
If we resize an event the red dotted line should hide.
you can use two separate events (one with the actual duration, one for the expected difference) and disable all actions (resizing, moving, etc.) on the dotted one.

Another option is to use the "event versions" feature:
It will let you define an event version that will be displayed above the event. It can have a custom start, end, color, text, CSS, etc. It can't be moved or resizes. You can use it to define the expected duration. There can be more than one version of the same event (e.g. for all previous plans).
