I will first and foremost reiterate that for the live action Transformers films, it's best to enjoy them as singular entities rather than try to map out any kind of continuity, even though the films do often attempt connecting visual or story elements. The next film, Rise of the Beasts, will be no different, hence my earlier article about it
not making a difference if it's a reboot or not.
People have since written in and commented, offering good points. The best one being that while the tropes of the live action Transformers films may be inevitable (and even enjoyed by many fans), at least a reboot of the continuity would mean that the films don't lead to the unconcluded story set up in The Last Knight. That is an excellent point, and for the reasons I will point out below, that may be what this franchise plans on doing with this film. That does mean, however, that while the continuity changes, the live action films would still be in the same universe, set up by Michael Bay and Steven Spielberg (aptly called Bayverse by many). And there in lies the question, would fans be ok with preserving the Bayverse but branching off into an alternate storyline/continuity within?
I bring this up because there were rumours of a test screening for the Rise of the Beasts, which included elements of time travel, connecting the Rise of the Beasts movie directly with the earlier Bay era movies and changing the past so that the storylines don't end up in the same direction as the previous Bay films, creating a new timeline. There was never solid evidence of these screenings, so not much attention was given to them. Those story elements are starting to resurface with the mention of the Transwarp Key (or Keys),
which we know will factor into this movie, and that was mentioned in the accounts of the test screenings. It may have been a lucky guess but, regardless, the "Transwarp" element does come from Beast Wars canon and it was the Transwarp Drive which let the Maximals travel through time originally. All to say, time travel can factor into this movie.
Other outlets have written similar articles comparing this possible plot point to the X-Men franchise where time travel was also used to create a diverging timeline within the same universe, creating new potential storylines (like the Apocalypse and Dark Pheonix film). As I read all this and put it together, I wonder if the fans who were asking for a reboot would be satisfied by this. While it would help the storytellers for future films, it still provides zero indication of fans getting what they want, which is a film focused on the robots with very few (to no) humans. It just means that the Unicron plot point from Transformers The Last Knight is abandoned, which would anger other fans. So ultimately, it looks like this doesn't benefit any fan. Those who want the Bayverse to die don't get that, and those who want to see a satisfying conclusion to the story the live action films were telling don't get that either.
But maybe this middle ground of a divergent storyline would satisfy some fans, hence the question this article asks: would fans be happy with an alternate timeline within the Bayverse?
