Confirming that the world as it stands today will more than likely get old and gray before we see another entry in the Half Life series of games, Valve Software has officially confirmed that they will not be putting in an official appearance at this year's e3.
So no new Left 4 Dead, no new Portal news, no Team Fortress stuff, and most importantly to about a billion fans of the game- no Half Life Episode 3, Half Life 3, or any combination of the words 'Half', 'Life', or the number '3' will be making any kind of showing at the e3 show.
Thanks for the update guys.
