Well, this render JJ posted yesterday looks like the fixed Scarlet to me: brain is the same width as redmote, so it's a Scarlet, there doesn't seem to be a lens mount and it looks pretty long so it could very well be the fixed version.

The angle of the shot may of course hide the mount behind the handle, and it makes counting ridges a bit hard, but still...
