Although as noted this could be referring to LEGO or Forces of Destiny, we'll wait and see I suppose.
There's a few gaps they could cover.....between ESB and ROTJ (A new take on "Shadows of the Empire"?) Between ROTJ and TFA (although apparently most of that era was peaceful, with the Republic in relative prosperity despite corruption, and the First Order gaining strength but not making any major moves until TFA. Plus it's probably best to leave the whole Snoke/Luke/Ren thing backstory to perhaps episode 9)....or maybe the Old Republic? Both CW and REBELS dealt in part with a somewhat revised ancient history of the Jedi vs. Sith conflict in some episodes; and Rian Johnson's proposed new trilogy won't be covering that era.
