Thanks for the securelist-link. It's indeed a better source for some technical details, also from a Kaspersky expert... But in the RT-interview the Kaspersky's chief malware expert says things that concur with what you share: "There is no reliable relation between Stuxnet and Flame as we call it…they are completely different. Because Stuxnet was a small application developed for a particular target with the specific objective to interact with industrial control systems and break them down. And Flame is a universal attacking tool kit used mostly for cyber espionage."
