I believe that while being in the alternate galaxy, Thrawn has started a bit of his own army and once Morgan Elsbeth comes to retrieve him, Thrawn and a bit of his own troops aboard the Chimaera and return back to the OG galaxy.

Once word spreads that he has returned, The Shadow Council could start regrouping to retake control of the galaxy with a new head in charge in Thrawn.

With Thrawn’s return, we could see The New Republic start to see it’s down fall and seeing The New Empire starting to gain its power again

The Senate could be corrupted, the New Republic could be VERY stubborn with its resources, which could cause some conflict.

But here is what I hope/wish the future could look like

----------------------------------------------------------------------------------------------------------------------

With Filoni’s rumoured movie which I think could be called “Heir to the Empire” to cap off the Mandoverse, we could possibly see the New Republic and the team of Din Djarin,Grogu, Greef Karga, Bo Katan and the whole Mandos, Boba Fett, Black Krrsantan, Fennec Shand, Cobb Vanth (including the biker gang), Ahsoka, Huyang, Sabine, Hera, Zeb and maybe even Ezra vs Thrawn’s New Empire, which could include the still remaining imperials scattered across the galaxy, Shin Hati and maybe Baylan Skoll (Tho he could be difficult to recast) and possibly Moff Gideon

Of course this is just fantasising, and I really wanting to see an Avengers: Endgame type of film seeing all these new characters all coming together from these shows to stop the new big bad of the galaxy.

Obviously for all this to take place, it would need to be a 3hr movie which looks like it isn’t the case but I’m still thinking about it.

Because I don’t believe that Thrawn will be killed in Ahsoka, nor in Skeleton Crew. I could see Morgan successfully bring Thrawn back to be the new heir. And for our heroes, they too successfully return, but this time reuniting with Ezra. They might’ve not have prevented Thrawn’s return but they got a new ally to help fight the new war. 

And at the end of the film I personally think Sabine and Ezra would be the ones to corner Thrawn and Ezra delivering the final blow to put an end to Thrawn’s reign (But that's just me) 

Plus IMAGINE the meetings between all the characters.I really want to see interactions between, Din Djarin, Bo-Katan, and Sabine (All different families and different Mando beliefs) 

I know it’s really early to even think about Dave’s movie but what do you guys think we could see in Dave’s Movie? (If it’s not going to be a cap off the the Mandoverse…I give up)
