So I remember Yoshi-P saying that the Benchmark would not have every option for creating a character. If this is true and we are missing some options, what options do you think will be there in the main game?

Horns- Since an Au Ra's horns are basically their ears I think we "might" get that option in the main game to change the horns on each face. This would also give more than four options for horns. (This one might be really unlikely.) I do not however think we will get a horn / scale coloring option as those seem lore specific.

Hair- Some of the hair options have extra horns in them. I think there will be variants of these same hairstyles without the horns. This would also allow for other races to have these hairstyles later one or when the expansion hits.

Limbal Rings(sp)- Probably an option to have different colored rings for your eyes.

Tails- Miqote have a lot more tail options in the current game so I wouldn't be surprised if we have more than four in the expansion.
