I'm just ready for IX to come out and be done with. Then maybe Disney and Lucasfilm can shift the focus of Star Wars away from the Skywalker lineage and do something unique. The EU has so much content from the Old Republic Era, they could use for inspiration. Not exactly copy content, mind you, that wouldn't fit the bill. Though I'm sure plenty of folks would be happy to see a Revan based trilogy, or a Darth Bane trilogy. I'd like to see something new from the Era of Jedi versus Sith.
Exar Kun was made canon, to an extent, with the Art of Solo:ASWS book. So perhaps even something revolving around him and Ulic Qel Droma.
I don't know, but anything that doesn't involve the current batch of characters, or the classic characters. If IX has another big PT tie in, fine. I'm curious to see what it is, provided it's not another mystery box, and the tie in actually makes sense. But once the sequel trilogy is finished, put it to rest. There's an entire galaxy of content to choose from, or create a new and unique story to tell.
That would be unexpected.
