I would say Highland nailed it on the Rian Johnson interview.
On the flip side, I shudder to think of what would transpire.
The whole "They fly now?!" thing seems pretty silly considering he has a crush on a space wizard and routinely travels the galaxy in mere moments.
The thing I absolutely can't wait to see is what the heck the hundreds of Imperial Star Destroyers are about. Those shots look awesome, and I'm a sucker for big space battles.
