I remember seeing that the Saddle Arabia horses did NOT have any cutie marks.
I wonder if the cutie marks are something exclusive to the ponies in the "Land of Equestria"
Maybe due to the abundance of magic?
But I can hardly wait for some lore about (the origins of?) cutie marks.
I'd also like to see the return of bugbutt and maybe an explanation to their origins.
Also would be nice to know what happened to alicorns.
Did they die out?
Pour all their magic (life force) into Sunbutt and Moonbutt giving them a ridiculously long life span, kind of like what they did to twilight temporarily.
We know it can be done (magic transference).
The removal of magic makes the ponies weak and it's tied to cutie marks because those disappear when the magic is no longer present in the pony.
And Twilight tried using magic to give AB her mark prematurely (and failed)as well as changing with each failure.
Also the spell Starswirl never finished manipulated the mane 6's (except Twilight who had cast the spell, therefore immune) marks.
What if a pony didn't like their special talent? Maybe this is how the new villain got started on the dark path.
OR what if the changelings are cursed Alicorns?
They have horns and wings like them.
