I just read the update about it being real promotional material, so I guess it's real.
Does Threepio become Rambo now? I mean the Resistance only has a handful of members left after the Battle of Crait (there are others somewhere that didn't answer the call), so does he step up and become a real battle droid now or does Rey and Chewie walk into a fancy restaurant and have Threepio hold their coats, so to speak.
