Nids have 4 units that do not have any model for them, Beastmen have 3 or so, Skaven has about the same. The only book I can think of that doesn't add new units in it that they have no model released for is Space Marines, but with it being the most popular and the biggest range I am not surprised on that.
So whats in GW's mind you think? My thoughts are that with so many good plastic kits they have out for most armies they need more stuff they can make new and sell. Which is good for the player as they get more options for each army that is out there and we get to see more awesome conversions till they model finally arrives in GW's line.
So any thoughts on this? Is it a good or bad move on GW's part?
