Possible Equestria girls series spoilers?
 
By analizing the new eg minis i noticed that the art in the box contains edited screencaps changing the characters clothes (except by trixie, also rainbow dash and rarity mini’s swimsuit doll aren’t leaked by now)
 
I comproved this comparing with that rare image talking about the 2018 youtube series, and the clothes are the same, so this confirm that the dolls will be available until 2018
 
By the way, not mentioned in the image but all of the dolls boxart includes a link to the eg youtube channel (the series is going to be aired in there), so yes, those would be spoilers, nothing about the series plot but we can see a closer look to how would they look just if discart the beach theme, this would be a episode plot considering that the eg minis always make the dolls inspired by a movie, short or special from the eg franchise
