This isn't a movie, folks, it's a TV episode, and they have nine more months before it airs. That's plenty of time.
Nine months until it airs, but only one month until it goes in front of cameras (which is the more important date here).
A month?! Sometimes the crew working on DS9
had less than two weeks to get sets, props, and costumes together. I'm much more concerned about the short shrift given to the 50th anniversary special than to this.
