Currently, there are 10 Star Wars films, and 12 if you count the Ewok films. The Last Jedi and the Han Solo film are just about done, it will only take editing the footage and it’s done.
Where are you getting 10 from?
7 main films plus Rogue One is only 8. If we count The Clone Wars that’s 9. Are you counting the Holiday Special for number 10 or am I missing something obvious?
