What do Ты think the CMC's cutie marks will be?

I agree with your idea of Scootaloo's mark, but I imagine it as the wheel of a scooter (maybe with a lightning bolt on it, to symbolize her idolization of радуга Dash). SweetieBelle's could be a bell, maybe three small ones (since I noticed multi-marks normally come in threes Ex. Applejack-three apples, Fluttershy-three butterflies, Rarity-three diamonds)

Applebloom's mark is going to be harder to interpret. Let me think it over.

Probably these...

Applebloom's may become a hammer, Sweetie Belle's a microphone или a Музыка note and Scootaloo's a racing flag. Of course there's no telling until they Показать it, but they are probably going to involve fixing stuff, Пение and racing.

I WAS GONNA ASK THIS XD. I agree with the ones Ты сказал(-а) (StarWarsFan7)

Applebloom eith a paintbrush или an яблоко blossom. Scootaloo, a scooter (duh!), and Sweetie Belle, a microphone или bell.

That's a hard one! I know that Scootaloo and Sweetie Belle have unique talents already; they just haven't figured that out. Scootaloo should get a scooter или something scooter или speed related. Sweetie Belle should get something musical, like Ты said. I'm not sure about яблоко Bloom, though. It would make sense that she would follow in the hoofsteps of her family and get an apple-related cutie mark, but she hasn't really shown any particular talent, so we can wait and see. яблоко blossom makes sense, yes, but who knows...

Applebloom's can be like an яблоко blossom with a bow on it as she likes to decorate
Sweetie belle's can be a Музыка note inside a сердце as she likes to sing and is so very cute
Scootaloo's can be a бабочка wings and a thunderbolt perhaps as she is a big Фан of радуга dash and is as быстрый, стремительный, свифт as a butterfly!!! :) I hope Ты all like my answer !!! :)

My thoughts are яблоко Bloom's CM being a golden painted яблоко for her talent of art, Sweetie Belle's CM being a note with a сердце for her musical talent, and Scootaloo's CM being a winged scooter wheel for her Любовь of scooter riding.

яблоко bloom something like an яблоко and a wrench
Scootaloo a scooter
Sweetie колокол, колокольчик, белл a bell
