Homefront DLC exclusive to Xbox 360

THQ has announced that all of the DLC for Homefront will come to the Xbox 360 first in a temporary exclusivity deal. The 360 version will also come with an exclusive multiplayer map called "Suburbs." This does not reflect changes in the release date in any other way. I'm really getting tired of these exclusives. I thought there was an agreement. Multiplatform is multiplatform and only 1st part stuff could be exclusive. Well probably not since Activision has the same deal with Microsoft on all Call of Duty DLC until 2012.
