Within the past several days, there have been several new developments for Playstation Call of Duty fans that we’ve compiled into a convenient single post.

First, the Escalation map pack is scheduled to be released on the Playstation Network on June 10th. The recently relaunched store is having twice weekly updates to catch up on its backlog of titles, and Duty gamers will benefit from this special Friday update.
With timing which is a little bit more than coincidental, several past Map Packs are discounted on the PSN in a sale that just went live this evening:
Call Of Duty 4: Modern Warfare Variety Map Pack – now $4.99, original price $9.99
Call Of Duty: Modern Warfare 2 Resurgence Package – now $7.49, original price $14.99
Call Of Duty: Modern Warfare 2 Stimulus Package – now $7.49, original price $14.99

Sony has also partnered with Activision to create a Playstation 3 and Black Ops bundle, meaning anybody looking to jump into the fray can do so for just $299.99. This represents a significant savings as gamers can now get Call of Duty: Black Ops and the First Strike Map Pack at no addition cost.
