Fallout: New Vegas Honest Hearts DLC Delayed on PS3

In an 11th-hour announcement, the Bethesda Blog notes that while Honest Hearts will be available tomorrow on Steam and Xbox 360 as scheduled, the PSN issues have caused it to be delayed until further notice on PlayStation 3.
Honest Hearts will be available on Xbox LIVE and Steam tomorrow, May 17th as originally planned. However, the add-on pack for PlayStation 3 will be delayed due to recent issues surrounding the PlayStation Network. As soon as we have more information on when it will be available we will let you know.
As far as I know, Sony is currently working through the backlog of releases caused by the network's downtimes, while also phasing the network back up. Honest Hearts will be part of that backlog, and hopefully it won't take long.
