Update: It's now official, Half-Life 2 has gone gold (thanks Steg).
It's now nearly official, neither Valve nor VU Games would comment on the topic but the word is out already, the long awaited Half-Life 2 has gone gold.
Earlier today, GameSpot learned from a locally based source that "the piñata has been broken" and the game has gone gold. Further evidence of the game's completion was a press release issued this afternoon touting the first review of "the entire game."
