I've looked up Splinter of the Mind's Eye. I discovered two facts about it.Well if you read Splinter of the Minds Eye an officially approved spin off novel they’ve been there already...
Boba Fett clones.What's a Mandalorian? .. it looks like Boba Fett and Carl Weathers is involved in this Disney Star Wars footage
Many Bothans died to bring us this video.What's a Mandalorian? .. it looks like Boba Fett and Carl Weathers is involved in this Disney Star Wars footage, this storyline is set 5 years after Return Of The Jedi.
I hate to say it but this stuff actually looks like the original trilogy ..
I think that's sort of been side-stepped, the troops in the new films are not clones, though Hux talks about bringing them back.
