According to the developer diaries there are tons of mechanics with exclusivity to specific countries: dynamic events, missions, decisions, and now even national ideas. This is very similar to what was done in EUIII and every other pre-CKII game.
It makes me feel disappointed. I didn't enjoy the system where Castille gets specific awesome bonuses just because it's called "Castille", or christian countries grow more powerful than others ones simply because they're christian. What worked best, in my opinion, is the CKII system where your power is based only on the land you own and how it is organized. The King of England didn't get special bonuses simply for being King of England, so you could jump in and play and not have to learn the country specific events and mechanics in order to play effectively.
Those are just my thoughts. I'd enjoy it more if it didn't focus on determinism so much.
