I'm thinking Hasbro does a "tiny" toyline for Rogue One similar to a Marvel movie, i.e. there's only 2 waves, all 5POA and pretty much all main characters. Remember that Episode 8 is out only 5 months after Rogue One. Therefore we probably won't see anything until SDCC for Rogue One, and Hasbro probably won't make too much more from TFA.
