User blog:Bovell/Escalation hits PC June 2. PS3 version of the DLC still unannounced.

Activision confirmed today that Treyarch will release the Escalation DLC pack for the PC version of Call of Duty: Black Ops on June 2. When asked on a date for the PS3 release, the publisher could only reply with "soon."

This turn of events is the opposite of what was seen with the first Black Ops DLC, First Strike, where it was the PS3 date that was given, and the PC one left unknown. However, it is reasonable to point out that PSN's recent downtime may have been a factor in determining when the PS3 would receive the Escalation map pack.

The Escalation DLC package was released on May 3 for the Xbox 360.
