However, in September 2015, Nordgren announced that CCP, while continuing with a five-week release cycle, would return to intermittently releasing large scale expansions for "EVE". She described the new release cycle as a "hybrid form", where expansions would be "a set of big, connected features" with no fixed number per year, while the feature-releases would continue to bring "quality of life changes, ship balance changes, visual upgrades" and other smaller additions. The first new expansion, announced at EVE Vegas 2015, will introduce a new modular starbase called a Citadel, and will overhaul capital-class ships. Its release date is set for spring of 2016.
