there was radiant AI in the OB demo, and they supposedly took it out since certain NPC's would buy everything in shops, leaving nothing for the character.
PLUS, NPC's would talk to each other by name, and this is when I got a huge mega-boner... why did they take THIS out?
Will they call eachother by name in SKyrim? Damn I really hope so. Let's hope Beth doesn't lie this time, what do you guys think? I'm willing to give them a second chance, and I have a feeling (if Skyrim is everything they say it will be) I'm going to absolutely love Skyrim when it's out.
EDIT-I didn't mean to use the word 'lie' and I should've known that would cause some steam here. Anyway, I cannot wait for the release, and I look forward to finally experiencing that RAI in action.
Well Oblivion has some awesome mods thats fixing and improve AI or demonstrate it flexibility

Radiant AI was very interesting feature, in combination with scripting make NPC behavior in oblivion awesome (thats was demonstrated E3 by Todd and expanded by mods), but there some flaws in in Radiant AI like high processor time usage.
I believe RAI was simplified for better performance mostly for consoles, thats was part of optimization for them, like divided by cells cities, oblivion was over optimized since no one know full power of nextgen consoles before.
But now I believe developers take in account old flaws but also take some inspiration from user created content.
