Rumoured stuff: Plastic Ogres, Ogres with cannons, Gnoblars (see pics below), Gnoblar Hunters. Their God is named Maw and they really like to eat.
Rumoured: Will be released after Storm of Chaos campaign!
There will also apparently be another type of hunter, no Ogre Cavalry and
Gnoblars are rumoured to have a weak missile weapon.
Also rumoured are "stupid" Ogres.
Another something is that they are strangely comparable to 40K's Tyranids. Big guys who carry cannons guiding small guys to swarm the enemy, with weak (missile) weapons. Both are very hungry too!
Ogres get "butchers" instead of spell casters. They will be the biggest Ogres, the ones who know how to cut the fresh meat.
From another source:
The Butchers are spellcasters with a new Lore.
Ogre Lords are named Ogre Tyrants apparently.
Gnoblar models can be stuck on Ogre bases to show that they are carrying stuff for them.
From Nuremberg: Ogre with Smilidon on chained leash called Hunter. Cannonwielding Ogres called Leadbelchers
