The Fall 2018 storylines of three of the shows that make up the Arrowverse - Arrow, The Flash and Legends of Tomorrow - all heavily involve potential futures. Whether this is part of some grand plan on the part of The CW or simply odd timing remains to be seen, but the possibilities have fans' heads spinning. They also have some fans seeing red, due to the perceived impossibility of the three futures existing as part of a single unified timeline.
In the past, changes to the timeline of one Arrowverse show have affected the others, with one of the consequences of Barry Allen's time travel on The Flash being that John Diggle's infant daughter, Sara, was suddenly changed into an infant son named John Junior on Arrow. It is also possible for potential futures to be averted and not come to pass. For instance, the events of Legends of Tomorrow since its first season have almost certainly prevented the dark future seen in the pilot episode. Likewise, the third season of The Flash was largely concerned with the unintended consequences of Barry Allen stopping his mother from being murdered by the Reverse Flash, resulting in a divergent timeline called Flashpoint.
To that end, here is a brief rundown of what is know about each of the three relevant alternate futures in the Arrowverse this fall. This rundown will examine how the individual timelines might connect as well as what sticking points might keep them from linking together. It is entirely possible, however, that no links are intended and that these futures could ultimately be undone by the events of their respective seasons.

Arrow's Star City 2038 Explained
Arrow season 7's premiere stunned Arrow-heads with a shocking reveal in its final moments. After detailing the efforts of a young man to reach the remote island of Lian Yu, where Oliver Queen spent most of the five years of pure hell that turned him into Green Arrow, the episode revealed that the young man was captured by a hooded figure who demanded to know why the young man had come there. The young man was revealed to be William Clayton, Oliver Queen's son, and the hooded figure was shown to be an older Roy "Arsenal" Harper - Green Arrow's first protege. This further revealed that what was presumed to be a flashback was truly a flash-forward, twenty years into the future of Arrow. So far, the full purpose of these jumps is unclear, although many fans suspect William is the new Green Arrow.
In "The Longbow Hunters", William revealed that a GPS device hidden inside a stone arrowhead his stepmother Felicity Smoak had given him had guided him to Lian Yu. The exact coordinates led to a grave containing a cache of Oliver Queen's old gear, including his first bow. This, in turn, led William and Roy to Star City, which had changed drastically since they had both been there. It was here that viewers learned that The Glades - the worst neighborhood in Star City in 2018 - had been gentrified into some kind of fascist gated community for the rich and the powerful, with the police force acting as their private army and the working-class forced into the largely lawless domain that Star City had become.
William and Roy ran afoul of the police in "Level 2", but were saved by Dinah Drake, who had apparently abandoned her Captaincy in the SCPD to become Black Canary once again. Dinah was also revealed to had trained Zoe Ramirez (the daughter of Rene "Wild Dog" Ramirez) to become a vigilante. Apparently, Star City's laws against vigilantism in 2018 had been expanded to include a shoot-on-sight order. Nothing was said about the rest of Star City's heroes from 2018, beyond Felicity Smoak being dead and Rene Ramirez not daring to show his face in Star City for some reason.
