City of Heroes' F2P Freedom conversion is still launching "this year," but if you're a current subscriber, you can check it out ahead of the pack.
Beginning on September 13th, existing players can participate in a headstart program that enables access to the Paragon Market cash shop as well as the brand-new First Ward co-operative zone. Paragon Studios is also promising official costume contests with prizes, dev-led groups in brand-new Incarnate trials, and live open-world invasion events on every server in addition to headstart-only "exclusive sales bundles and promotions."
Current subscribers are all set for the headstart; former players can still get in on the fun by reactivating and gaining VIP status now.
[Update: The official site now features a post on the headstart program, including details on the special sales and promotions.]
