phil kelly and robin cruddace confirmed to me and my friend that dark eldar witch hunters and necrons are being worked on. but theyt dont want to release stuff in parts so they are gonna keep writing them / designing models until they are satisfied they have enough stuff to release all at once. which is why nids and stuff are coming out earlier, they came up with ideas for them quicker.
they didn't say anything about dates for release at all though
robin also mentioned wht he was trying to achieve with the new nids. he said he wanted to make them seem as 'an alien force which are everchanging and evolving, but that we can at least partially understand them.'
so expect ALOT of options for tyranids. (scary)
SPACE WOLVES ROCK!!!!!!
