Yes. A key idea of Agile (maybe Scrum specifically) thinking is that you release and retrospect/rethink often, instead of long-term working on unlaunched projects from an ancient plan. I guess if you skip the rethink part than you aren't doing sprints property. An insight of Agile is that your have to pick either a feature based release schedule or a time based release schedule, not both, which is impossible and that time-based is better.
