>>23184627All of the dialogue for the Delta Episode was leaked from the demo, though. But you're right, the Delta Episode shouldn't have been revealed pre-release. Too many spoilers.
But I can kind of understand why they did it, though. ORAS are remakes of a game we already knew. There weren't supposed to be any secrets. Aside from new Mega Evolutions and the upgraded features, the Delta Episode was really the only "new" thing about them. The next games will be different, because we won't know what they contain completely until their release.
