Pretty sure they're going to completely avoid the EU stuff. If they stick to the 20 year between trilogies, than it will land in the time frame that Luke marries Mara Jade, and when the Solo kids first join the Jedi Academy on Yavin. The time frame is pretty open to anything for the first movie. However, 5 years after that is when the Yuuzhan Vong invade the galaxy, and that lasts for the next 5 years. That's a pretty huge moment in the EU, as many important people die, like Chewbacca. This would fall within the second and third movies.
It looks like they will destroy the EU to be honest. Oh well, I enjoy the books, but I am not a lore Nazi, so I couldn't careless as long as it is good.
