While discussing the company's lineup for the "back half of the year" during today's investor conference call, Activision Blizzard COO Thomas Tippl noted that is when "we plan to release the second map pack for Call of Duty: Modern Warfare 2."

The game's first add-on, dubbed the "Stimulus Package," debuted on Xbox 360 in March 2010 before hitting PC and PlayStation 3 in May 2010, offering five additional multiplayer maps in exchange for $15. As with the first, the second add-on will be available to Xbox 360 owners first before eventually making its way to PC and PlayStation 3.

Pricing for the second add-on has not been revealed, though Tippl noted that "the $15 price point has still provided a fantastic value to gamers... we think that has worked."

The next all-new Call of Duty, meanwhile, arrives November 9 in the form of Call of Duty: Black Ops, which is coming from Call of Duty: World at War developer Treyarch.
