Originally posted by Tenken347If anything, I think moving Star Wars to the winter season is a smart move. I know it's been historically a summer franchise, but these days that means competing with Marvel and DC, which typically do pretty well for themselves, as well as all the other summer films. That's a lot of competition, and although they did just fine financially, I think the prequels took some of the shine off of Star Wars. It's no longer the biggest fish in the pond, and the pond is becoming increasingly more crowded. The winter franchises don't run as deep, and the big dogs have mostly run their courses (I'm thinking of Harry Potter and Twilight here).
Disney also has Avengers: Age of Ultron scheduled for Summer 2015. I'm guessing they don't want to step on themselves.
It had somehow totally slipped my mind that Disney owns both Marvel and Star Wars. How I do not know. But that's probably 80% of the reason right there. You don't make your tent-pole pictures compete with each other. It's just bad business.
