First look through cards and you get the same number for each Warband. They both get the same number of faction specific cards in the same break down of objectives, ploys and upgrades. All the remaining generic are two of each, so to be shared equally.
Cards numbered with a total of 437.
I currently have 19 named generic and if the eight factions have the same number that's 232 cards. Big gap so expecting more generic in decks and/or more factions.
Looks like they're looking forward.
