I really hope that CA abandon the pre-determined outcome of agent actions (i.e. you can reload as many times as you like, the AI agent will always succeed when you load an autosave) as this was utter wank and a blight on some of their earlier games. It also worked the other way (i.e. if you tried to undertake an action it might always fail and this carried over to subsequent turns - so if you waited a turn then tried it would still always fail) and made a mockery of the whole ingame prompts about % of whether or not an action would succeed.
Since Rome I have pretty much given up on using agent actions because of this rancid and fetid crap. If it is included in 3K I will never buy that game (and you can hold me to that).
I hope that they will also stabilise the engine - as games progress the AI turns tend to get much longer and more boring. I do tend to Alt+Tab when the AI turns are generating to do something else but in later turns this regularly causes the games to crash. I hope they have realised this and sorted it.
