6. Kylo Ren will begin to turn to the Light
It’s the classic story of redemption that Star Wars has become famous for. Now that we know for sure that Kylo Ren is actually Ben Solo/Skywalker, then we can assume he will take the path of his grandfather, and eventually turn to the Light Side of the Force. I don’t think he will be fully redeemed by the end of Episode VIII, but I do think that the death of his father (by his own hands), and his defeat at the hands of someone he considered to be inferior, will serve to help begin his change into the good guy.
