Half-Life 2: Episode Two trailer; Alyx is hurt!

A clever h4xx0r has managed to extract the trailer for Half-Life 2: Episode Two from the recently released first episode. Notable points of the trailer:

• zOMG Alyx dies?!
• New baddie! An extemely potent looking and fast moving tripod.
  
• A voiceover by Dr. Eli Vance which goes as follows: "we're done running. This is our chance to take back out world, we're not going to lose it a second time."

Episode Two should hopefully be out by the end of this year.
