Hasbro is restructuring the way Hasbro Studios, in charge of its TV and film operations, reacts with the rest of the company, such as its toy business.
As for what this means for My Little Pony, only time will tell. It could mean more show-to-toy or toy-to-show integration, more "show accurate" toys, and/or higher quality products all around, the latter of which is always a good thing. Hopefully, as many collectors have said, this will lead to Hasbro looking into better quality control for its toys as well.
