There has been some talk about Dark Elves, whether we will see them in November or like this bit says, October. Of course these seem to be rather vague, but perhaps something more on Dark Elves will appear. Dark Elves would be a release I could get excited about.
Please remember that these are rumors

Dark Elves are due in October 2013, it is said be a complete new book and not just a wave
New elite infantry kit, possibly witch elves, executioners or black guards.
(If new witch elves, there will most definitely be a new Cauldron of Blood piece)
Rumors I've heard:
New large monster type, probably 150x100 base type. Though could be anything, a kit of options to build a hydra, manticore or other monster types.
Plastic harpy kit with two options, neither of which have been specified except it is harpy related.

Sure I can contribute, Exexutioner and Black Guard share same kit, with black guards having alternate caped back piece, head, and halberd.
The weapons are almost interchangeable without any work done no matter what torso you use for the body yes even if 2 handed.
My speculation is there will be no new manticore as chaos already received a new plastic one during storm of chaos.
Lastly regarding Cauldron of Blood. It is a hybrid kit with old witch Elf element for 1 build. While the new variation is like Empire War Altar.
It has a special aura similar to EOTG called ??? blades that is like a whirl wind of magic blades that damage surrounding enemies emitted by khain's hatred.

Look for many new Dark Elf models on launch, focusing on those "that needed it" *hint, hint*
I would assume "that need it" means:
Executioners
Black Guard
Witch Elves
Cauldron of Blood
Chariot
Warriors/Crossbowmen
And I saved the best for last:
Morathi
GW prioritizes metal ugly models for updates before ugly plastic ones, so the talk of new Executioners/Black Guard and Witches would make sense.
