Looking at the releases for FFGs other Battlelore game, Battle of Westeros, might shed a little light on what they might be planning for Battlelore 2nd Edition:
- The core set, which contains two factions (Stark and Lannister).
- Two $30 expansions, one for each of the two factions.
- Two more $30 expansions, also one for each of the two factions.
- An individual $30 expansion... seemingly works with both factions? (I don't play BoW)
- A large, $70 expansion that introduces a new 3rd faction to the game, equivalent to those in the core set + expansions.
Personally, I'd rather see a whole new faction first rather than a 2nd wave of expansions for the Daqan/Uthuk, but I could see a neutral unit expansion of monsters and mercenaries, or a hero expansion of legendary units.
