Well it was revealed in the novel/chapter/story book ''[http://mlp.wikia.com/wiki/Chapter_books#Pinkie_Pie_and_the_Rockin.27_Ponypalooza_Party.21 My Little Pony: Pinkie Pie and the Rockin' Ponypalooza Party! ]''that Pinkie Pie does have a third sister, though her name was never revealed, only that Pinkie's dad Igneous Rock refered to her as Pinkie's "Older Sister", so appearently the MLP:FiM creators are just trying to show us fans that the MLP:FiM Novels really are Canon to the actual cartoon or something like that.
