Comics Nexus picked up on an interesting comment from Dan Jurgens about his miniseries, Time Masters: Vanishing Point. In addition to telling a Rip Hunter Story and acting as the flip side to Batman: The Return of Bruce Wayne, his third goal is “to put a few pieces in place for Flashpoint, for which Geoff Johns is sculpting some incredibly fun stuff down the road!”
CBR has more on the miniseries, though considerably less about the Flashpoint connection.

Reading about the miniseries Time Masters: Vanishing Point makes me interested in reading it now!
