I'm very curious what the Keyword situation will be when the Datasheets drop. Negavolts are obviously chaos, so not relevant to Admech, but will they be Heretic Astartes? They're obviously not CSM in the literal sense, but they might need that keyword to be playable. Same deal for the traitor guard and renegade psyker. (R&H would be a better fit, but GW-primary doesn't use FW keywords.)
If they intend for all 8 protagonists to be playable together in 40k, does that mean they're all Imperium? Even the Eldar and the Kroot? Will the Eldar player have Imperium and Aeldari, or will Eldar players actually not be able to use her?
And of course, what the hell faction could the spindle drones possibly be!?
