I feel for you, but this is really "not Agile". The point is shipping working software every sprint, and during the sprint you are not supposed to be interrupted until Sprint demo. It's on the so-called Product Owner to prioritize what's next sprint, projections, etc, and a Scrum Master is supposed to help protect you from distractions. I've done this style of agile before, and it's great. However the issue is many mgmt types still only caring about when "all of this will be done?", and also teams and people which can't think incrementally.
