Not to mention that Pablo Hidalgo (at least I think it was him) said in The Clone Wars Legacy video that even though those stories haven't been released yet, they still consider them canon. So if they're important, then they will surely be released at some point. Especially if (spoiler alert) a certain character we all know is Fulcrum in Star Wars Rebels.
