Regarding the finale: I think that Starlight Glimmer will try to prevent the Rainboom and thus prevent the Mane Six from ever existing. It will thus show an alternate time-line with the Six all having different cutie marks and different lives (there have been a few fan-fictions that have explored this theme before).

Then what? Either Twilight follows Starlight back in time to try to stop her or...

Starlight has to learn that it isn't all about her. The alternate time-line is a bit like IDW's Dark Mirror Universe. Without the existence of the Six, the alternate Equestria is on the verge of catastrophe with Nightmares Moon and Star at war, a Sombra-corrupted Cadence pursuing her own evil path and Discord running out of control. Starlight thus has to find a way to undo what she has done before the factions blow up the planet (and her in particular). Her only allies are the Six who, in this timeline, are largely ineffective and very unpleasent misfits.
