couple of things i noticed in my few hours of test run
-Lords seem to be capturable, atleast AI keep taking other lords as prisoners
-Ai actually takes castles from other factions now (this is nice)
-every faction has alternative leader who you can help to power (atleast i think so, didnt have enough renown to actually get the quest yet)
-NPC's have relations now, some like each other, some hate each other
-i got ambushed in a city at night by some thugs, that was a funny suprise

-you can join factions as a hired blade (get paid and a change for vassalage after certain period of time, allthough traditional straight vassalage is still there too)
Loads of very nice changes, have to say it's great fun
