Microsoft has revealed during a keynote at this year’s Consumer Electronics Show that when Infinity Ward releases the upcoming DLC for Call of Duty: Modern Warfare 2 in the spring it will be as a timed-exclusive for the Xbox 360.

More interesting is the omission of the PS3 from the announcement completely. While PC won’t see the add-ons at the same time as Xbox 360, it was still mentioned to actually have plans for releasing the content. The lack of announcement pretty much sums up the state of PS3 DLC over the past couple of years–though if you want a true microcosm of delayed content for the Playstation 3 you can simply look at the individual case of Fallout 3.

Regardless, at least two map-packs are currently planned for Spring 2010 release on 360 with PC to follow, and in all honesty it just wouldn’t make any sense that a large chunk of the MW2 fanbase would be left out of purchasing additional content for one of the highest grossing titles in history. I’d put money on a resolution of the matter in the form of a separate PS3 announcement sometime down the road, but not necessarily soon given the track record.
