With the rumors going around so far (Pokebeach's hasn't been disproved yet and it's getting more evidence too) it looks like that Fairy will be immune to Dragon, which would significantly weaken Dragon-type STAB. But the rumors also suggest that Dragon will be it's only resistance, so Fairy looks like a more effective secondary typing. This is all based in the Pokebeach rumor but we know for a fact that Fairy was made to check the power of Dragons (as said in the round table) so I think it's pretty safe to say that some form of resistance will be there. As for actual Pokemon goes we don't know a lot yeah, but hey at least we know that we'll have a Water/Fairy Azumarill. Why do people not like Vanillish? I thought it looked fine.
