The graphic update isn't even completed yet. The release is less than 2 months away. They'd never delay the release unless they really felt it was absolutely necessary.

I feel that the graphical update backlash is mostly coming from a very small minority, like smaller than the amount of people who actually play Hrothgar, or maybe even Roegadyn.

The demands people have been making range from inconsequential to nearly impossible. From demands of adjustments based on observations caused by the new lighting, which people need to be able to actually play the game to get a good handle on, to demands of having an entirely optional graphical update opt in, effectively demanding the team develop two versions of the game at the same time while anticipating an unrealistic zero consequences for it.

Among actual design decisions there's some reasonable takes in a slew of hyperbole and narrow distinctions. A lip shape might take a 30 degree curve originally, and now it takes a 28 degree curve, and will be described as radically different and lore breaking. Some of the changes people are going crazy about I have to actually check 3 or 4 times to determine which is the new version and which is the old. Meanwhile the male viera face that actually looked quite different has been buried under all of this and I can no longer find that thread.
