Lot's of similarities, although this new design looks more humanoid without the elongated 'skull'. Even the 'jaw' is evident. I have always been convinced that the original SJ is not all suit - we see some of it's own self showing through, the jaw just being one example. This new design looks to show a similar thing, like the 'helmet' is more of a 'face-plate' that engulfs the face of the wearer, not the entire head.
Liking it.
