Sony Japan says that its PlayStation Network and Qriocity online services may not come back online until the end of May. Speaking to http://www.bloomberg.com/news/2011-05-09/sony-s-playstation-qriocity-ser... ">Bloomberg by phone, spokesman Shigenori Yoshida told the publication on Sunday that the services would remain offline and that the company is uncertain as to when they will be back online. Sony shut down the PlayStation Network and Qriocity April 20 because of security breach initiated by unknown hackers.
Yoshida added that the company is testing and adopting improved security measures and that the service would "restart the services fully by May 31."
Of course "fully" means fully operational with all services intact. Sony has said in the past that it would restart some of the services sooner than later.
