What do you want to see in Episode 9?

I mean, sure, that'd be FUN.  But look what the previous two films did.  
-Mary Sue is now super Sue
-Resistance is down to nothing, now we need a "spark" of "hope" to start a new one..
-Kids can use the force for things beyond enhanced feeling or senses completely untrained
-First Order has limitless resources and apparently owns the galaxy 5 minutes after TFA having only fired 5 shots from a mega weapon
-Or is the Galaxy ungoverned?  Who knows?

Even if he is Plagueis...to tie up all the garbage plot lines and to overthrow a power as developed as the FO from a band of what, 20 people? - it just doesn't sound like they'll be able to tell all that and wrap up the trilogy in one more movie.  Such a sloppy mess. 

Would have been more interesting for Luke to meet Plagueis, as was mentioned in a thread...so maybe we'll get a film full of Force Ghost.  Why the hell not at this point?

ha, maybe you'll get your wish and he'll get his own 'solo' film. I'd probably watch it if those familiar with the Plagueis story said it was decent...I just don't know if I'll get to it for a while...

I would like to see Rey become evil and back.

Clean slate for the galaxy! I like it!

What about the Outer RIM allies?

Yeah, where the hell is Wedge???  They made a big damn deal about him and Lando still doing their things in the Aftermath series and we still haven't seen either one in a ST film.  What the hell?

Just another reason TFA/TLJ are disappointing as a combo.  I let it slide that Wedge and Lando weren't mentioned in TFA because TFA had to introduce us to the new cast and it brought back pretty much everyone else from the OT.  One film can only do so much.

But in the Aftermath books - which are supposed to work in tandem with the new movies - Wedge not only appears, but plays a pretty big role.  I'd say he was probably the ninth most-featured character in the trilogy (there's a band of six new heroes - one of whom makes a cameo in TFA by the way - and two main villains that are the most-featured, but Wedge being by far the most featured supporting character and having several major plot investments).  And when the story's over, he's still alive.  So where is he?

Same with Lando.  There were two interlude chapters that featured Lando in the trilogy.  They had nothing to do with the main plots except to show that the Empire's power was quickly waning.  So why show us Lando (Lobot too!) is alive (and kicking ass by the way) if he wasn't going to make a grand entrance in a film?

But then again, they made a big deal about Vader's red light saber being found by a dark side cult (and used!).  They also made a big deal about Boba Fett's armor being found (and used!).  These were also interlude chapters that had nothing whatsoever to do with the main plot. So you'd think that adding these side stories to the book in between TFA and TLJ were indications that Rey finding Anakin's blue light saber at Maz's castle was not just an Abrams mystery box, but was in fact, a cleverly unfolding plot about how powerful relics were going to play a role in the ST's plot.  But just like how the TFA novelization alluded to Snoke in several ways as a bridge character between the PT, OT and ST, it's all just garbage in the dumpster that RJ lit on fire.
