Star Wars 8 & 9 on Familiar Ground?

Wochit Entertainment is saying sources in Lucasfilm have told them that Tattoine, Mustafar, & Endor will pop up each in 1 or both of the upcoming Star Wars sequels completing this new trilogy started with "The Force Awakens". We all know how Skywalkers feel about sand, & I know y'all can't wait for another dose of cuddly warrior bears. Mustafar seems risky though knowing how much everyone just adores the prequels & everything associated with them... However, the Force is strong with the folks over at Lucasfilm right now. They pulled off "Rouge One", & most people already knew the ending going in just to deductive reasoning. Most intriguing though, is wondering what these places look like 20+ or more years later?
