What do 당신 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 무지개, 레인 보우 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 또는 a 음악 note and Scootaloo's a racing flag. Of course there's no telling until they show it, but they are probably going to involve fixing stuff, 노래 and racing.

I WAS GONNA ASK THIS XD. I agree with the ones 당신 said (StarWarsFan7)

Applebloom eith a paintbrush 또는 an 사과, 애플 blossom. Scootaloo, a scooter (duh!), and Sweetie Belle, a microphone 또는 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 또는 something scooter 또는 speed related. Sweetie Belle should get something musical, like 당신 said. I'm not sure about 사과, 애플 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. 사과, 애플 blossom makes sense, yes, but who knows...

Applebloom's can be like an 사과, 애플 blossom with a bow on it as she likes to decorate
Sweetie belle's can be a 음악 note inside a 심장 as she likes to sing and is so very cute
Scootaloo's can be a 나비 wings and a thunderbolt perhaps as she is a big 팬 of 무지개, 레인 보우 dash and is as 빠른, 스위프트 as a butterfly!!! :) I hope 당신 all like my answer !!! :)

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

사과, 애플 bloom something like an 사과, 애플 and a wrench
Scootaloo a scooter
Sweetie 벨 a bell
