There's lots of innovation happening if you ask me and even among the 'copycats' the bar is pretty high as compared to 2 years ago (see related post about the 35$ themeforest themes). Adii's post sounds a little self-congratulatory to be honest (not very surprising since they have accrued a lot of credibility & success). But...it's pretty conceivable that today's Woothemes is tomorrow's DIYthemes.
