New listings that have been removed from Amazon's UK branch seem to have hinted at an upcoming toy line built around the idea of ponies crossing over with other properties, similiar to what we are seeing with Transformers in the near future. The listing had a pretty specific description, hinting at a future character named "Plasmane"
They also mention "My Little Prime" for Transformers, and "Power Rangers Morphin Pink Pony", meaning we will most likely be seeing a bunch of crossovers out of this.
On a side note, these are using the retro pony molds, so oldschool.
Check the description out below.
