Not really unexpected at this point, but to have this come up is rather sad. We have been hoping for a long time that the Bretonnians would see the light of day somehow, but for now, they are following a great line up of extinct Games Workshop armies. Squats, Tomb Kings, and now the Bretonnians.

Sad heads'up - if you want to get your hands on some Bretonnia stuff, try to get it now. Afaik they won't be included in the Order Great Alliances book, and will have an exodus similiar to Khemri. Soon.
