Damn. I never would have found the link in that last topic were it not for this one. Of course in a way it does deserve it's own topic. Personally I like the new model, even though it's unfinished. The claws ought to be shorter and denser, like chisels or railspikes, not long and spindly like tentacles. The only other complaint (which isn't really a complaint considering that the new model matches the original concept art more closely) is that the dense organ in the rumbler's 'chest' no longer matches the organ that you extract and research. However it probably doesn't matter that much since it's not like the hybrid organ looks like any part of a hybrid's external body.
BTW what's the news on the monkeys, or the SHODAN model? The latter was supposed to be really freakish and scary from what I understand.
