Left 4 Dead 2 PC Now Pre-Loading on Steam
To begin the process, right-click on Left 4 Dead 2 in Steam's "My games" tab, select "View pre-load info..." and follow the steps. Once the download is complete, Valve promises that "when the game is officially released, you'll be able to play it immediately."
Thanks to Dion for the heads up.
