While not on display to general attendees, Hasbro did have some Star Wars: The Force Awakens items to show at London Toy Fair 2015. Jedi News is reporting that Hasbro held a special closed door, invitation only, presentation at the event. this was only open to very large retailers, with reporters being specifically barred from entry. Those who did attend were given a Star Wars: The Force Awakens tote bag.
Not much to go on here, I know, but at least we can hope that Hasbro may show off products sometime before San Diego Comic-Con, as they will not have The Force Awakens toys at NY Toy Fair in a few weeks.
