There was something odd in today's Rebel's Recon. Notably, with the real life Chopper droid crating himself up, and that crate having a UK flag stamp on it. It certainly makes you think that there may be some REBELS related cameos in ROGUE ONE.
As I've said from the get go...how these two are not interelated would be mindboggling. Why not feature some of the rebels in a scene if only for a fan wank. I was originally convinced that Sabine, Hera or Ahsoka was going to star in this...until proven wrong I wouldn't doubt it
It is also baffling that there have been very leaks, no trailer yet almost nothing...Star Wars media is so weird (and that includes the lack of information coming out of their toy licensee)
