Why do all the available styles look just like the default?

I was under the impression that with the new CSS capabilities of 4.x that designers would be free to design more creative styles. However, all I seem to find are are styles that are barely more than color variations on the default style. There are some glaring issues with the default style like: The "+ Post New Thread" button, and the use of what appears to be Times New Roman for the "What's New" heading in the CMS. These, and other, attributes obviously appear poorly chosen for the surrounding style.

Where's the great styles hoped for with this release.
