I think the Black Speedster will not be in the fixed timeline. They said a speedster that will be introduced later on the season. Also if Tommy Merlyn didn't die in Flashpoint and him being Prometheus, then that's also a permanent change. Eobard Thrawne being on Legends Season 2 as a regular will probably also be a result of Flashpoint.
