Will Friendship is Magic finally see a half dozen group of male ponies from the ORIGINAL version of MLP? The Big Brother Ponies: Tex, 4-Speed, Slugger, Steamer, Salty, and Quarterback?
If the Mane Six have their baby male dragon Spike, then maybe a G4 version of the Big Brother Ponies would have a female baby dragon.
Would Fluttershy's brother belong to a new version of the Big Brother Ponies?
Perhaps a new version of the BBPs would be the crew of an airship powered by steam engines, flying around Equestria carrying mail for the Equestrian Postal Service as well as passengers.
