what about the bretonnians and beastmen and wood elves? any plans on bringing them into the mix?

There's already a few beastman units for chaos anyway so it seems unlikely that they'd be released as a separate faction. There's one bretonnian card already (Battle Pilgrims) so more seem reasonably likely. No sign of wood elves yet though.

well, you can almost make a whole deck out of " neutral " skaven cards. they should add the brets in a large quantity to counter the skaven. and they should make a wood elf faction. : )

Oh, you can definitely field enough skaven to make a full deck with just a few other neutral support cards.

And yes, I agree with you on bretonnians and wood elves, though I'd rather see ogre kingdoms first (as true neutral units).
