So far, it looks like we know half the player cards in the set, including all the Spirit cards. Is there anything else we know that I am missing?
Card # - Title - (sphere and type)
1 Dwalin (Spirit Hero)
2 Bifur (Lore Hero)
3 Narvi's Belt (Leadership Attachment)
4 Durin's Song (this is card 4 or card 5) (Leadership Event)
5 ??? (Leadership card)
6 Veteran of ? (Probably a dwarf, full name unknown. This is card 6 or card 7) (Tactics Ally)
7 ??? (Tactics card)
8 Khazad! Khazad! (Tactics Event)
9 Zigil Miner (Spirit Ally)
10 Untroubled by Darkness (Spirit Event)
11 ??? (Lore card)
12 Ancestral Knowledge (Lore Event)
13 ??? (Neutral card)
Of the 165 cards in the box, 35 are player cards (2 heroes and 11 x 3 = 33 other player cards). That leaves 130 cards that are either encounter cards or quest cards. There are 9 new encounter sets in the box. On the spoiled encounter cards it lists how many total cards there are in each of those sets. See my post further down this thread for info on the encounter card set sizes.
