So for the purposes of data:
Daqan 7 expansions - 2 not yet released
Latari 6 expansions - 6 not yet released
Uthuk 5 expansions - 5 not yet released
Waiqar 7 expansions - 2 not yet released
Feels like we have probably 1 Latari and 2 Uthuk expansions yet to be announced, least in the short term. Makes me wonder tho how many more expansions per army we'll see. Does FFG pause at 7 ... 8, 9 per army?
Course then the next question is how much of what isn't yet released is going to be out before worlds?
