“Market reasons” is the reason that Funcom is giving us on The Secret World’s official forum for the game’s launch date being pushed back. What that means is anyone’s guess but the new launch date will be July 3rd with Early Access beginning June 29th for preorder customers.
Not to worry though if you’re already hooked because Funcom is also expanding the beta weekends program to cover the extra time. Hopefully this will give Funcom some time to iron out the bugs and make sure the game is polished and ready for a launch. Whatever the real reason is, best of luck to them, and to you as you try and wait for the release.
