According to this report, the villains in Episode VII are reportedly a group of Jedi hunters, sort of like the Inquisitors (but their source didn't call them that). These are apparently adepts, or at least disciples of adepts, from a group of Force users that Emperor Palpatine created during the time of the Galactic Empire. These Jedi hunters were never Sith, but worked to ensure the survival of the Sith and were quite powerful. With the death of the Emperor, their goal is reportedly to resurrect the Sith, and are not the galaxy's ultimate evil power.
Apparently, if this rumor is true, there is no New Republic, and the Jedi hunters are the reason for it. Luke Skywalker, and presumably any disciples/children/nieces/nephews he has, have been somehow fighting the Jedi hunters for 30 years. The report says that the Jedi hunters probably never went after Luke during the original trilogy because Darth Vader declared him to be off-limits, since the Sith had plans for Luke. But now that Vader is dead and the hunters are the stewards of the Sith, they would go after Luke Skywalker. The Emperor also apparently left a plan for them if he was to ever die.
The source said that the Jedi hunters that the film would focus on would be played by Lupita Nyong'o, Adam Driver, and David Oyelowo. Nyong'o and Driver are both confirmed members of the cast (and Driver has long been rumored to be playing a villain), and Oyelowo has been rumored to be part of both Episode VII and Star Wars Rebels.
Obviously I don't know if this is true or not, but it seems like it could be a plausible story. I like the idea of this story as well. I think it makes sense that Palpatine had adepts that helped preseve the Sith and the Empire. We already know that such characters are canon anyway; the Inquisitor is the main villain of Star Wars Rebels, so perhaps some of the Jedi hunters like him survived and carried on with instructions that the Emperor left were he to ever be killed.
One thing a lot of Star Wars fans, particularly Expanded Universe fans, might pick up on is that the report (as well as a number of previous rumors) says that there's no New Republic. Taken just at face-value, that doesn't make any sense. After all, how could 30 years have gone by without a new government, even with interference by the Jedi hunters? But when you think about it more, you realize that you can get so caught up in the semantics and miss the fact that there could be some sort of proto-government, like an alliance of planets, that just hasn't formed into a New Republic proper yet.
Even in the real world, if you look at the United States, it took the country 115 years to have all 48 continental states, and a few more decades to bring Alaska and Hawaii in as states. It stands to reason that it would take at least 30 years to recover from decades of tyranny and really form a new government, especially if there's interference from dark side adepts.
