Modern Warfare 2's first batch of new content, the "Stimulus Package," was given a release date on the PS3, but not their platform of choice. Don't fret, folks -- the game's Steam listing has been updated, and now includes a May 4 release date for the new content. As a reward for your patience, Steam will even knock $1.50 off the price of the maps for pre-orderers. See? Good things do come to those who wait.
