I don't understand why people can't be happy with having 10 races already. They want to crossbreed the races so they will look "cooler" but not really much more. If you want to have red eyes you can always go and become a vampire, cuz they often have red eyes...
I think people are quite happy that the 10 ES races are in the game. But this is a forum for discussion, speculation and throwing out ideas and talking about them is what we do. It really has nothing to do with dis-satisfaction for an unreleased game and more to do with human nature.
OP, I usually play dunmer characters, an in Oblivion, I actually modded two of my longest running favorite characters and took out the red eyes, as their back story, limited as it was, did have them being of mixed heritage, and something of an outcast to dunmer, thus giving some motivation for being a little bitter and stabby and also willing to explore the world and adventure a bit.
