I have read [this press release][1] a couple of times.

> In order to give maximum creative freedom to the filmmakers and also preserve an element of surprise and discovery for the audience, Star Wars Episodes VII-IX will not tell the same story told in the post-Return of the Jedi Expanded Universe.

Is this material set after Jedi or published after?

Is it also saying that only things published as "Legends" are now non continuity?

I have read that it is only Films + Clone wars + Rebels that are now in the main continuity but can't see this sourced by Lucas Film Story Group. Does anyone have a reference for this?
