Half-Life 2: Orange Box will contain: Half-Life 2 Half-Life 2: Episode One Half-Life 2: Episode Two Team Fortress 2 Portal It's being released this Fall, assuming they don't delay it (again ). Regarding the latest graphics technology, it will contain: A better lighting model Better shaders Larger textures Take advantage of multiple cores Introduce their new "cinematic physics system" (which obviously make cinematic scenes look insanely impressive to watch.) Regarding the content: A new character A new enemy A new weapon A new vehicle Regarding the storyline: You'll learn a lot more about the G-Man. A major character will die (I'm assuming Alyx). Episode One was 4-6 hours. Episode Two will be 6-8 hours. I don't know about you guys, but this is my favorite game and when I buy this and play it, I want no interruptions whatsoever for the solid 6-8 hours (or more if it takes me longer).
