Perhaps this post from Pushkin on warseer will clear this up :

I had a really nice chat with Andy Hoare about blood bowl. This is done and will be out before Christmas, the models and the sprues were all done and they look great.

Humans and orcs are in the box, and then skaven and dwarves will be next. The pitch is reversible and has a human pitch one side and an Orc one the next side. Once they get skaven and dwarves out done they're going to do a similar double sided pitch for them. In terms of other plastic box sets they are going to do an elf team and one other team. Everything else will be resin. Special characters are in the works, but rules for some of them are already done.
