Well it is true that there is speculation of it, but keep in mind it's acknowledged as speculation and therefore isn't 100% confirmed that it will happen. (It was also speculated that Tirek turned Luna into Nightmare Moon and that was proven wrong)

It was speculated here quite a bit. And I think it's more likely because in Friendship Games, Twilight Sparkle (the one from Equestria) said that she was dealing with some "time travel loops". Put this together with The Cutie Remark reminding everyone that Rainbow Dash's first Sonic Rainboom is what led each of the Mane 6 to get their cutie marks.

Also, if this is before Friendship Games, then it means the timeline will be restored. Even if Twilight follows Starlight through time and therefore remembers everything, permanently altering the timeline would mean Sunset Shimmer would be un-reformed and the Humane 5 would still be apart
