I think many of us wanted an orc without a hunch, but Blizzard mentioned various times before that they wanted to preserve the feeling and look of the old models in the new ones. It sucks that the Thrall-like models will be out-of-reach, but that's just the way it is, I guess.
I am sad too, but I didn't make any huge expectations.
(Wish Blizzard would allow you to choose between straight and hunched)
