I think there are many people who hope to see the same characters again, with the same personality and in the same story in the same world, I think it is necessary to clarify that the next generation will not be located in the same world, so they will practically not exist the same characters, we can only hope that the concepts that these characters represent and / or their designs appear. For my part, I would like to have Luna, a pony that is related to dreams, Sunset Shimmer, because that name is too beautiful to discard. From what I can see, they will bring back at least part of Mane Six, Twilight, Rainbow and Pinkie, they are the three most popular so it is quite certain that they will be the protagonists or at least secondary characters, I can also Spike, a dragon that He lives with ponies, although I don't like the idea too much. But in reality all this depends on the world that will be created for this generation.
