Director JJ Abrams has a passion for intrigue and unseen mystery. This is self-evident in his Bad Robot tweet pertaining to Apple's Watch announcement this week.
The background design will be familiar to Star Wars fans. It's Imperial in origin and seen aboard the Death Stars and Star Destroyers of the original trilogy.
I'd suggest it's most likely foreshadowing the resurgence of the Empire following its defeat at the Battle of Endor in Return of the Jedi. However, some fans speculate there's a new Death Star in Episode VII.
Do you think there'll be a Death Star III? Let me know in the comments below.
