Was already stated many times that they are implementing more styles. Obviously they would include the styles already made first with the alpha.

The point isn't totally to preview all of the new things coming in 2.0. The point is to test and find bugs and to fix players to do things that would stress the game to see how it holds up. How is adding all these planned hair styles and such going to help that?

Also, you're lucky they are presenting this game's development as an open book. Most people have to sneak their way around to see footage.
