This just in. Awesomeness abounds. A 3rd wave including DE Battleforce, Talos Pain Engine, Dark Cronos Parasite Engine, Dark Eldar Venom, and Scourges are all being released in June.
I personally see a lot of great ideas coming from the use of both "engines." The scourges are fantastic and the build looks great. i would however like there to be two Battleforces. One with 20 wyches and one with 20 Warriors. That way you can focus on one kabal more. Kind of like what the imperial guard do with catachan and cadians.
