Original Description:
 
So fellow bronies we have our beloved “Mane Six”, there counterparts the “Canterlot Seven”, and the later introduced “Student Six”. Now what about these three new lovely Mares? What should there group moniker be simply the “Mane Trio” or something a little more original like the “Prime Trio/Three”, “Leading Trio/Three, or “Central Thrio/Three”? I’m leaning more towards the “Central Trio” myself assuming they want be picking up three more mane friends along the way.
 
You saw it here first folks from yours truly “The New Pony” if one of these monikers goes foreword you know who said it first.😉
