There wasn't always new Star Wars. There was a period in the 80s when Star Wars was effectively at rest, without much by way of cartoons or expanded universe books or even new toys. And new movies? Forget new movies. There were three films, and that's all we needed.
That lull in Star Wars is almost unthinkable to a new generation, and it's about to get even less thinkable: at this year's CinemaCon Disney made it official that starting in 2015, with Episode VII, they'll be releasing one Star Wars movie a year every year for at least six years. That's a lot of Star Wars.
Of course it won't all be main saga stuff; the main movies will be released every other year. The fill-in years will have solo, spin-off films, like the rumored Yoda or Young Han Solo movies. Still, in six years Disney will create exactly as many Star Wars movies as it had previously taken 28 years to create. That's a doubling of Star Wars theatrical product in a very, very short amount of time. So it's official: they're going to oversaturate the market.
It's interesting that Disney made this announcement now; I've heard there has been quite a bit of behind-the-scenes agita about Episode VII, and that the rapidly-approaching release date is part of the problem. This would have been a great time to reveal a relaxed schedule, not to double down on the very tight one they already have. I guess Disney is committed to this plan, no matter what the creative types say.
