The two interesting things will be the Mage Knight universe and the clix patent. I don't know too much about the universe, but I thought they had comics and such for a while. I'm not sure if it has a fan following enough for someone to buy it rather than simply make their own fantasy universe.
The Clix patent could be licensed out to basically anybody that wants it. Basically could end up taking HaloClix or the Horror stuff and make non-collectible board game style versions like they did for that pirates thing. Those things are likely to sell as cheaper toys compared to some of the crazier stuff like $80 Millennium falcons. Or someone could hold onto it and make some kind of come back in 4-5 years.
I think all the other material is at least housed license wise outside WizKids (Shadowrun, Crimson Skies, Battletech) such that there shouldn't be any major changes to the non-mini lines.
