Haemonculi are a favorite of many Dark Eldar players, and I have liked them for years. From this rumor it appears that the Dark Eldar will once again focus on expanding the new line of models focusing on the creations of the vile Haemonculi.
Please remember that this is a rumor

the Haemonculi will be a big focus of the new book as the Wraiths were with the Eldar. There is a possibility of the models being a WD release initially. The Wrack kit doubles as a entirely new unit that focuses on chemical weapons.
The Bane have even more exaggerated proportions that looks like it can rip a Dreadnought to shreads bare handed, very cool.
