I just saw that... insanity.
From the chat where I saw it:
[18:59] Maybe she misspoke and meant a film every two or three years. =P
[18:59] But I mean... with the money and people Disney can mobilize, they could probably do it.
[19:00] I assume 7, 8, 9 will be part of the "original saga" and if they decide to continue that, I can see a movie every couple years.
[19:00] But at the same time, they have access to the whole galaxy.
[19:01] So they could do movies with totally different characters and unrelated stories about the underworld, or Boba Fett, or clone troopers, or stormtroopers, or pirates, or Jabba, or anything really.
[19:01] And they could do some of them animated in various ways.
[19:02] So they probably could do multiple films a year.
It does, however, make me worry about oversaturation and the quality drop involved with that.
