Half life 2 Episode 1 (http://ep1.half-life2.com/) will be coming out June 1st so I guess there is always that to look forward to. It will follow the story directly after the events in half life 2.
In the meantime I've mostly been playing Oblivion plus a bit of Age of Empires 3. I've finished the main story and the fighters guild missons, so now I'm just traveling around Cyrodill raiding random dungeons and doing the occainsional quest. Ho-hum.
Heres the site where you can download the trailer for HL2 episode 1
