Most will likely agree that the whole Half-Life 3 joke has worn a little thin. I am certainly tired of it, and just wish Valve would announce the thing and get it over with. Well, apparently that's not going to happen at E3. The company says it has no plans to do so. Sigh.
Of course, Valve could be lying and readying some wonderful announcements that will fill your socks with candy and rainbows, but I wouldn't bet the farm on it.
