Still, assuming this information is legitimate, the idea that Episode IX will include important connections to the Prequel Trilogy does sound fascinating.
Though keep in mind that something could change down the line in the scripting process that could affect how direct said connections are.
Personally, I doubt we’ll see something terribly explicit, like a new army of battle droids.
Given the presence of characters like Luke Skywalker and Leia Organa, as well as The First Order directly rising from the ashes of The Empire, it’s no surprise that the current Star Wars sequel trilogy is more closely tied to the Original Trilogy.
