Looks like Skaven are up next. Nice looking Linerat to start. Also, halfling team available as an addon. I like them more than the GW trees and for $30 USD, that's a pretty sweet deal.
$169 right now will get you the M&G game, a full 16 player Dwarf, Human, Orc, High Elf, Lizardmen, Necromantic Horror, and Halfling team, plus an Ogre, a Troll, a Deathroller, a Krox.
Hopefully the rats are unlocked as SGs, and if so that's a lot of BB value plus you get a James Hewitt designed game... It's kind of crazy. I'm a bundle of mixed emotions, because for me I have all the official GW teams with the exception of the High Elves and Necros.
