I also think.. perhaps that Ezra at an older age could possible be a part of Episode 7-9 or stand alone movies... perhaps?!
There's something to that BOY for them to make a WHOLE animated series about him... and it's NOT small!! Ahsoka was a key character, but her story isnt over yet either... neither is Darth Mauls, Starkiller, Mace Windu (he literally COULD have survived that fall), Ventress, Mother Talzin, and others... they ALL could pop in at any time!!! :)
my personal opinion is... even mace windu went into hiding, but he never learned to communicate thru the force like Yoda learned how to... but Yoda could have contacted him, IF he survived that fall, just like he did with Kanan... BUT the ONLY way Yoda was able to contact Kanan was by Kanan USING the force MORE... but many jedi HID their force talents, bcuz they were HUNTED by the empire and people like Inquisitor, Star Killer, Vader and Palp could SENSE whoever was using the force within a radius from them... so maybe Windu had to completely HIDE on Coruscant until he could leave... BUT there is a possible story there, dont you think? :)
