Yeah, I think it was only a matter of time before the "classic" marines were phased out after Primaris was introduced. Anyone who thinks otherwise hasn't looked at the cost of renewing injection moulding machines.. Still, the Primaris models are pretty cool. Especially the newer models now they seem to have finished "testing the water". I'm curious how they're going to handle some things, because Terminators are.. well. They're one of the defining units IMO. But I don't know the fluff behind Gravis armour, so.
