Please note: First and foremost a date has not yet been confirmed for release.
Felix has publicly said that a Dark Elf army will be on the cards, though at what point and after which kickstarters are finished, he has not said, other than "can take a long time."
He has also said that alongside the Dark Elves we can expect to see lizardman regiments, though he describes them as "Saurians" and not lizardmen and has hinted that they will have a "more draconian style than lizardmen style"

No idea who is sculpting the Dark Elves but I may have an idea or two as to who will be doing the Lizardmen.
