Sorry it`s no rainbow power series at us yet
And I have not found any clear home pictures of them. On promo photos they seem to have regular length of hair. But on home ones their hair look longer. If ponies really do have long hair why Hasbro decided to hide it in the package ? what modesty!
Remember all previous editions shouted slogans on the boxes... like wow extra hair what a rare pony
May be you have some pictures to share please ?
