We know that the Viks are a November release. With the realease scheduele seeming to be 2 crews a month, that would suggest there is a non-gen-con box along with her.
I guessed personally at the brewmaster, releasing him would mean that all 7 factions have had a crew released (As the BM is dual faction), and give a firm footing for us to go round again and get another guild and resser in January.
This would also mean that the Brewmaster, the only brand new master in wave 1 (As Tara is not getting her regular model until wave 2), will be out intime for christmas.
