What we know besides:
Burgundians have full BS barring ring archer armour and plate mail is an unclear case.
Dying cav didnt generate gold, this bonus might have died so
TCs are able to produce vills and flemish militia after the rev costing 800f450g
They have BBT
Sicilians block 50% of all bonus damage
Donjons replace watch towers, thus the UU is trainable in feudal age
EliteSearjants have like 4/4 base armour making them the child of a tk with a huskarl, together with the ability to make build donjons themselves, they could bring a really nasty tower spam rush without a lot of vill idle time.
Castle skins are unique
