“I asked Forgeworld about xeno stuff such as: Ad-Mech, Knights and Eldar. They are very enthusiastic about that whole Ad-Mech stuff, but they said it is unlikely to happen anytime soon. Eldar were mentioned as playing a role in IA-9.
Forgeworld said they have no plans for the mighty Phantom titan. Moving onto the remaining Eldar superheavy tanks (Void Spinner, Stormserpent), they mentioned that they are planning to make the Void Spinner, but if they ever get around doing the Storm Serpent it would probably a completely different design. So the current scoop is Void Spinner-likely (HOORAY!), Storm Serpent-not (BOO-HISS!)
Turning towards Ad-Mech Knights, it was said they were looking into making some Imperial ones but their overall design would likely be altered from the “Barony stuff” from Epic to a smaller support titan concept for the titan legions. I gather they intend to make one. Eldar Knights were ruled out as highly improbable.”
~Standard Caveats on all of this, but a lot of this is very encouraging. I’m all for some love for Eldar in an upcoming IA book, and it seems that everyone and their brother loves Mechanicus Knights as a concept. Also for the record if any of your Forgeworld guys are reading this… Storm Serpent, you know you want to! For the rest of you, what titans and superheavies from the 40k universe are you most dreaming of?
