Actually this is incorrect. Its a 10 year contract with a minimum of 8 years of Destiny content. Starting with the development of Destiny 1 and ending with the release of the Destiny 4 major expansion. Release schedule is 1 Destiny game every 2 years with 1 major expansion every 2 years. The idea here was to alternate and keep the series fresh. With a couple years under this contracts belt, the Destiny franchise will in fact take up the whole 10 years if not more.
