The first pictures of new tyranids are out. First up is the new hive guard pack. New weapon options that look even more like a harpoon/grapple. Supposedly not a dual kit.
The other new rumor is that warriors are getting the broadside treatment and getting bigger and placed on 60mm bases.
This one I hope is not true. I like the current sculpt, I have 30+ of them. Also, warriors are the core chassis of most nids, raveners and lictors will look out of place. They are supposed to be the terminator equivelant, so they should stay 40mm.
