Originally slated for release at the end of March, has quietly pushed back the release of 2 downloadable episode "The Passing."

Kotaku reports the based on the UK "Inside Xbox" show that airs over Live.

"The Passing," which is the first download for Left 4 Dead 2, sets up a meeting between the cast of the first game and the new characters in the sequel. Three maps are promised.

Valve hasn't provided any reason for the delay, only reassigning a vague "spring" release for the download. In addition, a price of 560 Points is provided as a peace offering in light of the indefinite release date.
