Don't think of it as "loosing EU" think of it as a 'recreation".

The stuff we love about Star Wars won't cease to exist just because they want to make a movie universe clear of any contradictions or lore confusion.

I'm honestly excited about this new stage in Star Wars history. 

As far as JJ, he will most likely do great things. During a behind the scenes interview on the first Star Trek reboot, Abrams stated that doing a Star Trek movie was strage for him because he always considered himself a Star Wars geek. We are going to get the movie we want.

But I would melt in Thrawn was indeed in it.
