New Black Ops DLC leaked

Australian arm of retailer GAME slips news of next premium download for record-breaking shooter

GAME Australia has, presumably mistakenly, released details of what appears to be the next DLC release for Call of Duty: Black Ops.
Called 'The Escalation Pack', it apparently contains five maps – Seize the Zoo, Take the Hotel, Secure the Convoy, Raid the Stockpile and Survive the Call of the Dead.

It also suggests a concrete release date May 3rd 2011. That, of course, will only be on Xbox 360 as both PS3 and PC will get the content later thanks to Microsoft's exclusivity agreement with Activision.
