The first bit of substantial DLC for Left 4 Dead 2 is coming a bit later than expected, but isn’t that always the case with Valve time? All jesting aside, Valve finally pinned down a release date on the DLC today, confirming that it will hit Xbox Live Marketplace and Steam this Thursday.

While Valve has yet to make a formal announcement, the information comes courtesy of the latest Xbox Live release schedule. Free on PC, The Passing will carry an asking price of 560 MS Points or approximately $7 in Earth dollars on 360.
