Again, nobody ever said that Disney would take the Jedi out of the Star Wars franchise. If Rey decides not to be a Jedi, and there are no new Jedi established, for these two films it doesn't suddenly mean Disney stops exploiting the Jedi. They will be milking the Jedi for the next 50+ years if they can. There are lots of avenues to exploit Jedi merchandise, especially with the spin-offs. Just like Lucas was exploiting it even during the long stretches of time between trilogies.
