What can be concluded out of the recent DLC announcement?

[Kraut and Tea]

I guess I am not the only one who had a closer look on Steam and read through the descriptions there.
It left me with a few questions I wanted to pose:

Sparta’s dominance over the Helots allows them to maintain a larger slave population

Seems like slavery will play a far more important role this time than it has in the last games. Maybe one will be capable to raid enemy towns for them or by taking prisoners during battles.

New Cultural Traits – All Greek States benefit from a bonus in battle when defending their own or an allied territory, a bonus to wealth generated by their capitals and an increase to the rate of cultural conversion within their borders.

Has religion been replaced with "culture"? And what exactly is meant by "culture"? Will it be a single thing which agents and buildings can convert others to, or is it something different combined with religion, philosophy, technology and other????

Greek States have their own new set of military, economic and cultural victory conditions

So victory will no longer be limited to simply owning a certain amount of provinces or having their allegiance? Will having a certain level of technological advancement, access to certain trade routes and goods and owning a certain amount of money also determine if one wins or not? I would like that.

Athenian fleets may be honoured as Children of the Aegaean, improving the ramming ability of their ships whilst allowing them to secure more income when raiding; Spartan armies may be remembered as Peers of Leonidas, improving their melee defense capabilities and reducing their upkeep; the armies of Epirus may be feared as Hounds of Molossus, granting them greater charge bonuses whilst allowing them to keep public order problems in check.

So one can ramm ships (not really suprising). But what does it mean that units can be "honored"?????? - Does this mean that hero units can be created during the campain through units gaining expirience?????

Slavery will bring benefits to your faction but too much slavery and revolts happen. Sparta gets bonuses in repressing slaves.
I think Cultural Traits are like Faction bonuses similar to in Shogun 2.
Greek States are like that special kid next door. I think that the victory conditions are just for them.
I think units have a chance of getting their special faction bonus, but not always.

Just like Shogun 2 certain factions will be able to field units with free bonuses. Athens=naval bonuses; Epirus=cav bonuses; Spartans=infantry bonuses.

Epirus seem like a neat faction, I wonder who will be the faction leader for them when the campaign starts. It would be cool if Pyrrhus was still around but I'm guessing Helenus will probably be the faction leader at the beginning.
