I know I'll probably start an argument over all this, but I wouldn;t mind seeing a green Godzilla with reptilian skin, at least if it fits in the movie's art style and the characters origins.
I would have a black or gray Godzilla if we get a remake of the 1954 film or something similar with a Godzilla that is dark and brooding.
Personally I wouldn't want a dark film like the 54 incarnation. However, that doesn't mean I want to see a shallow, Transformers style film. I would want a film with great battle scenes yes, but also a GOOD story, maybe something like Godzilla vs. Biollante or Godzilla vs. Destoroyah.
The Godzilla I would like to see would have green and black reptilian skin, KIND OF like this, albeit much darker:http://img.webme.com/pic/s/spinosaurida ... tiacus.jpg
I remember seeing a Spinosaurus design back in Japan in a game similar to Dinosaur King that had the exact color I wanted to see on Gojira, but I can't seem to find it...
As for my take on Godzilla, here's a description:
My take would have a very humanoid body structure similar to the GFW Godzilla. Would have a moderate amount of dinosaurian features, but not to the point where it overpowers the design/makes it a generic T-rex. Godzilla would have SLIGHTLY digitigrade legs and a somewhat S-shaped theropod like neck, pronounced hand talons, a baryonyx like "hook" claw, an alligator like tail for swimming, and reptilian green black skin with texture similar to this:http://1.bp.blogspot.com/_hS9aGr5gOrY/R ... saurus.jpg
