Please keep one major fact in mind. Genesis is a commercial theme and these guys are doing nothing else than working the whole day on Genesis and its child themes. I have a day job that has absolutely nothing to do with WP, themes, or even the internet. In addition I make some extra money with highly customized WP and BP themes. In my spare time I take care of my family and Thematic. Gene is the second developer working on Thematic and even he has a pretty tough day job to fulfill. So. We are talking about 2 developers with a very limited amount of time. (#)
