Chantal Strand already confirmed she recorded lines for Diamond Tiara this season: I think it’s safe to assume the two of them will be playing a role.

I suppose someday Silver Spoon will be running through Ponyville waking everypony up by yelling, “The Trottingham ponies are coming! The Trottingham ponies are coming!”.
