I hope that Skyrim will feature the different races actually sounding and being different. I want all the races to have their own accents. I want the bow-legged versions of argonians and khajiits. Oblivion was too vanilla in that department and I really like immersion. I want to know that I'm talking to a certain type of elf because of his accent and hand motions to convey whatever point he/she is trying to make. I want to know the type of culture that a khajiit lives in based on their manners and the way he conducts himself or herself in public. I know that not every person in a certain race can't be exactly the same because they would just become stereotypes but I don't want them to all act like the majority race for the region I'm in. So I don't want all the orcs to be like nords. In Oblivion they kind of got the point across that each race has it's own culture but they could've taken it deeper.

A Khajiit in Morrowind once told me that the concept of property is hard for Khajiit to grasp, which is partially why they get a reputation of being thieves. I think that could be cool to implement in Skyrim. Maybe the perfectly decent Khajiit courier is imprisoned for a few game days for taking some food. It could be interesting.

I agree - some strong cultural tendencies and norms would be very nice to see, in full flight.

What we will get, I have no idea.
