Recent rumours state that, per End Times, there is no longer going to be an actual Warhammer world.
Instead, pretty much all the minor races got killed off and the world blown to bits, only to retain it's form in side of 'bubbles' of reality that float around. Whenever they bump into each other, the armies of each go to war.
They also reduced the playable armies to 6.
1) Humans (Dwarfs/Ogres)
2) Chaos (Beast/Warrior/Daemon)
3) Elf (High/Dark/Wood)
4) Skaven
5) Orcs & Goblins
6) Undead (Tomb/Counts)
