It was already non-canon to begin with. "Expanded Universe" was a nice way to say "Yeah, go fuck with your toys, but that's not my Star Wars". The last part was literally said by George Lucas.
If anything, now it's more canon than ever. Because Dave Filoni was such a huge fan of Star Wars that he started pulling things from the Expanded Universe, like motherfucking Thrawn. I mean, Darth Bane's force ghost appears on the Clone Wars TV show talking to Yoda!! That's top level fanservice for the Expanded Universe right there.
I've got not doubt we are having Old Republic movies sooner rather than later. Revan is definitely going to show up.
