Lol it's all speculation, and someone is just going to be lucky and get it right. Many people claim it's inside info, but it's mostly crap. There's no way to tell if any "leaks" are real, unless you report them all. Chances are, when you report them, Nintendo will already know.
There won't be a fairy type. It will be a fairy pokemon and it will either be Normal or Bug. Normal for the Clefairy fairies and Bug for Illumise (I know it's not a fairy but it's as close as it can get) or Tinkerbell.
