As downtime for Sony's PlayStation Network lingers on, Gamasutra sources report that Sony has asked some developers to install new SDKs on their PlayStation 3 devkits prior to the service coming back online.These new SDKs come following the massive data leak earlier this week, which compromised user information including passwords, addresses, and perhaps even credit card information. The new update is not necessarily related to new security measures.In a Sony statement following the security breach , the company said it will start "re-building" its system to protect PSN from future incidents.Although the service has been offline since April 20, Gamasutra sources said they have received no information regarding when PSN will be back up and running.Earlier this week, Sony's Patrick Seybold said that the company should have PSN back online "within a week" of April 26.A development source has clarified to us that it's possible the SDK update is unrelated to any new PSN security measures. A separate unnamed source on Develop claimed the update is unrelated to PSN issues. We've updated our piece and apologize for any confusion.]
