Right now, this is what they see on the schedule for future releases after the second wave on Dark Elves in November:
Jan – Tyranids
Feb – can’t recall at the moment (Might be Hobbit related)
Mar – Dwarfs
Apr – Imperial Guard
May – Wood Elves
The big surprise and newest addition is the Wood Elves. They are long, long overdue for a new book and replacement plastic kits, and will likely see a big shift to bring them in line with the new Dark Elves. ASF for all Elves seems like a given at this point.
