In the next patch we'll have:
1) a totally reworked Ancillaries system. Retinues will be much more culture specific, and less generic, than in vanilla, and you'll be able to see Roman patriots, Carthaginian merchants, mistresses, and Greek orators.
2) speaking of Carthaginian merchants, they'll be making an entrance into the world of Classical Italy, available *only* to Carthage. There will be interspersed several highly lucrative resources throughout Italy, which largely only Carthaginian merchants will be able to sit on, and reap more fortunes than in Vanilla, which would be necessary to keep the Carthaginian empire and military machine afloat.
3) Etruscans will be getting a face-lift, with a brand new interface, and no longer having Aztec settlements (erm ):
