MSW has this today: http://makingstarwars.net/2015/09/star-wars-the-force-awakens-knights-of-ren-symbol-other-jedi-implications/
Basically there's some card game where characters have symbols to identify their faction. Finn only has a Rebel Alliance/Resistance symbol, but Rey has one for the Jedi Order in addition to that. It's not a very comprehensive system (there's no symbol for the Empire/First Order and Kylo Ren is listed as a Sith), but this does seem to suggest that regardless of whether Finn is the one who ultimately ends up with the Skywalker lightsaber, we'll see Rey using some Force too.
