Sound

Jay did not do any voice acting for Diablo III. (He has done death screams in the past.)
Jay did not have to get too involved with sound. The team just did an amazing job on their own.

Difficulties - Normal to Hell

Majority of Diablo players just play through normal, have a great time, and then are done.
For the more core players, nightmare is where it starts, thought most might feel inferno is where it will truly starts.
Jay says he can get through nightmare in less than 10 deaths.
Hell depends on his current character build.

Inferno

Jay Wilson states that he can not clear less than half of act 1 without less than 10 deaths.
He states that in Inferno if you find a really hard pack, you are not really able to skip them, while in nightmare and hell you can kind of just move around them.

Character Customization

They had character customization in for the Barbarian at one point. He had about 8 or 9 different hair styles along with other changes. But you could not tell when he was covered with armor. It was just a lot of work for something that had very little benefit.
The player puts effort into selecting this look that they never really end up seeing it and its delaying the player getting into the game.
One of the things they liked about Diablo II was that you picked your character and hit start and go!

Mac Client and Languages

If they see a demand for more supported languages for the mac client, they will add them!
