Star Wars :The fall of the Rebel Base

The new Star Wars film's [no.8 coming out soon] name has been leaked and it is rumoured to be called 'the fall of the rebel base'. John Boyega says it is to be the darkest Star Wars film[ not including the clone wars films or rouge 1] ever made! The plot has also supposedly been leaked but some of the things in the script that were leaked don't really add up- as it says in the script that Lando comes back wearing a Jedi cloak type thing but we all know that Lando Calrissian isn't force related.
