So according to Making Star Wars, Thrawn is coming to Star Wars Rebels... but it won't be until Season 3. Obviously this is just a rumor at this point, but if it's true then he's almost certainly coming to Armada!
This would make sense to be honest. X-Wing had Mara Jade awhile back, but had nobody else from the Zahn books. They've been no stranger to EU stuff, but strangely shy'ed away from Zahn's stuff. It could be a deliberate delay, waiting until 2017 for Thrawn's glorious debut!
What do you think, could there be any truth to this rumor?
