The box cover shows which two factions will predictably be in the box. As if there was any doubt it would be FFing Sigmarines and Nighthaunts. There's also a flying cave squig coming to go with that troll.
So it looks like we're going to be getting some kind of Wood Elves, Dwarfs pretending to be Squats, Night Goblins, whatever the Troll comes with as a separate warband, gumpy fat barbarian ladies, a Tzeentch warband with funky stuff in it and the two gangs that come in the box.
I'm actually excited for many of these. I like the wood elves, I like the Kharadron gang. I like the Tzeentch warband and I might be partial to the big fat chubby ladies as well. I'd enjoy playing against the troll and goblins but I don't know if I'd want to own them or not. Overall I think season 2's going to be a lot of fun.
