They are 'not necessarily cannon,' meaning that we're going to override parts of the EU when making the films. 

Which is fantastic. The EU basically consisted of Mary Sue Skywalker humping the force into new planets about a hundred times while cloned blue hitlers jumped out of space to do force-drugs, and STAR SMASHERS had to come in that were star tie fighter sized but stronger than the death star that could.....

.... I mean.....

Effing FUCK trying to fit a new movie into THAT moldy mold. If you liked EU, keep reading it. I loved parts of it, totally. I'm glad they're not giving a shit when they prepare for these new movies...... movies come first, and books based on the movies come second.
