Our strategy at Obox has always to be on as many marketplaces as possible. Themeforest and WordPress.com do stand out though and in terms of revenue per-theme, WordPress.com is mega.

We all knew that at some point WP.com would open the flood gates, it had to happen as this industry is simply too lucrative to turn your back on.

That being said, I too hope that the high coding standards that are expected of WP devs remain. Their reviews of our themes have been a huge lesson for my team and everything we apply to our .com versions eventually filter down to our Themeforest/Obox versions.

To those of you who are new to the marketplace, I wish you all the best! :)
