Bad news for me too. I am started converting my site to Drupal..
I though Drupal usage was rising. What is the point of releasing new Drupal themes, if not supported after 2012? Of course the price is low (half), but even with this price, who would buy a theme for eg Drupal 7, if he can not upgrade it to Drupal 8?
But as I can see from this topic, there is no interest in Drupal in Rockettheme members.
