Here's some more interesting tidbits regarding the plot. Take it with a grain of salt. However, I can say this with 100% certainty, almost everything was leaked about the prequel trilogies before they were officially confirmed. I remember when the story board depiction of the Jango VS Obi Wan fighit leaked on the internet, and everyone jumped in to say it was fake. And guess what. It turned out to be true like many leaks in regards to the trilogy's plot direction.
• Star Wars Episode VII will be set 30 years after Episode VI: Return of the Jedi
• It will indeed feature the Skywalker/Solo children coming to the peak of their powers
• The Jedi Order has been rebuilt with Luke Skywalker as Grand Master
• A disciple of Emperor Palpatine aims to rebuild the Sith Armies of the Old Republic and destroy the Jedi where the Skywalker children will be thrust into battle and face their inner demons of their Skywalker lineage.
