Prediction: Luke will say "I am your FATHER"! Thanks JJ you did it again ! :)
JJ you are the best. I especially liked it when you had Spock scream Khaaaaannnn! at the end of Star Trek Into Darkness. You completely killed the Star Trek franchise in less than 2 movies. Here for your Star Wars finale you probably want to cap off completely copying the OT movies by having Luke this time say "I am your Father!" to Rey or better yet if you want to be really really twisty say it to Kylo!
You are so clever JJ!
