As expected, Microsoft’s exclusivity period for the Modern Warfare 2 Stimulus Package was rather short lived. Publisher Activision today announced Infinity Ward’s first round of DLC will make its way over to the PS3 and PC next month in North America and Europe.

Consisting of five add-on maps, look for it to hit PS3 on May 4, with a European release following on May 5. The PC counterpart will hit Steam worldwide on May 4.

If the record-breaking sales on Xbox 360 are any indication, expect PS3 and PC owners of the game to gobble up this content.
