Now I'm looking forward to when the ultimate code dives start coming out, like they did after ID released their source code for Quake / Doom / ect... All the interesting tricks / shortcuts that people found when they really started picking into the code base. Heck, even style, and how they've organized and managed such an enormous code-base would be neat to see a deconstruction on.
