I dunno about that
I kind of agree with Rich's prediction that this is their least accurate prediction ever
round deflector dish = the filmmakers just didn't notice or care, or possibly will be a throwaway line where Lando fixed it up the way it used to be
Luke's lightsaber = Rey repaired it, there's a visible black area in the center where the split would be, and it allows them to do a montage of her repairing the lightsaber while Kylo repairs his helmet, it's so symbolic
plus we have seen and know about some new characters in the film and if you're time traveling to go revisit old characters you don't also introduce new
Abrams "fuck it" means it's going to be a glorious mess somehow but I don't see what they would do with time travel
although I like the idea of Rey being Shmi Skywalker because then it goes back to, she was a nobody from nowhere but ALSO started the most powerful family in the galaxy, which means anybody can be special, just like those little kids at the end of TLJ
