I have confidence that they will add Jar Jar into the trilogy.

No-oooooooo!!!

Well, they added Gungans into the end scene of Return of the Jedi for the 2004 Special Edition. Even giving them the final line of dialogue for the film and whole Original Trilogy: “Weesa free!”, so it unfortunately wouldn’t be that surprising if he was added elsewhere in the OT in some future SE release.

Matthew Wood says he did the voice for the Gungan that says the “Weesa free!” line. And claims it is a simply a random Gungan:-

Sorry for the bump. It still annoys me to this day whenever I see an “official” release of ROTJ from 2004 onwards.
