I'm pretty sure that's why the game was delayed though... It's nowhere near completion and they couldn't release what they currently had on Sept. 30th.
I haven't lost any faith in Valve though... I think they'll come through and release a kickass game with awesome AI and physics, but I think the main point of the scripted sequences we saw in E3 (which were SUPPOSED to be AI) were pretty much there to make us think the game is almost finished, and that a Sept 30 release might actually be possible. I think we all know now that it wasn't possible.
