More Half-Life 2 Preloads

Steam News (thanks Frans) has word that further preloads of Half-Life 2 content over the online content delivery service are now underway, supporting a rumor of Dubious Quality suggesting a gold announcement nears. Here's word on the preloads:
The sixth phase of the Half-Life 2 preload begins to Steam account holders today. This will allow users to download the Half-Life 2 maps in encrypted form. No purchase is required to pre-load Half-Life 2, but is required to activate the game. The moment the game is made available, those who have pre-loaded and purchased the game via Steam will be ready to start playing.
