the prime, first off notice the small adrenal gland crawling on his
back. that is a new bit, does not exist at the moment. Also the back
vents are slightly different than a raveners, this are thicker and
stouter, while a raveners is more like a fin.
On the actual
warriors, there is the fleshy part exposed on the knees and ankles, this
is at least twice as much as is exposed on the current warriors, and
they currently only have one pose.
You can also see that the
bonesword arm is different than the current finecast bits. On the back
of the primes sword is a knick, where the current ones only have a knick
on the front side.
So enough subtle changes that reveal it is
probably a new kit, but stays in line with the current models. probably
like the marine tactical box. I'd say the small crawling mite on the
primes back is the most guaranteed way of saying it is something new.
I originally saw these over at The Warzone . From what I've seen most people are initially calling these just a kit bash (my self included). When Tyranid Veteran players have to do a double take, it means the models fit the current line well.
I feel the warriors might be getting a Tactical squad treatment, a new box, but will basically look the same in the end. The real question is, is the prime part of the box, or a clamshell?
