It was revealed a few a while back but there will be a polybag associated with Star Wars: The Force Awakens which is a C-3PO (5002948) minifigure polybag. As you can see, this version of C-3PO is a little different from the usual versions we’ve seen since has a red arm for some reason which will be revealed in the movie this December.
There are two different offers for the polybag in the US as far as I know. One is a LEGOLAND Florida special offer where purchases of $35 or more from September 7 to September 28 will net you on of these polybags. The other offer hasn’t been officially announced yet but I heard that it will be available at Toys R Us with a certain purchase amount in November. Check out a short review of it from PromoBricks below.
