The other place to look is GDC, most big companies will release powerpoint of the presentations they give.
Here's a few links, some of this might be useful, but I'm not sure...
Bungie: Halo3 stuff mostly Lots of interesting stuff here, not just programming stuff.
Bungie.net : Inside Bungie : Publications
Naughty Dog: Various examples of work created for Uncharted.
Naughty Dog, Inc. :: Purveyors of Fine Video Entertainment
There are lots more, if I can remember where they are I'll update this post.
Let me know if they are any use.
Cheers
Chris
