I ESPECIALLY hope that the rumor about the types that are supposedly weak to Fairy is wrong.
Dragon makes sense, at least. It makes sense science-y wise (what with the whole "slay the Dragon fairytale" genre). It also weakens a competitively overpowered type and brings it down the the realm of mortals (or it'll at least TRY to).
Fighting would only make PARTIAL sense, however. Granted, it WOULD weaken another extremely powerful and popular competitive type; however, it doesn't really make sense science-y wise. In the fairy tales, the fighter is usually the protagonist; any fairies that opposed him would usually be the villains, which would mean that if anything, Fairies should be weak to Fighting-types, as opposed to the opposite (though I don't think that they should spin it like that; the LAST thing the meta-game needs is for Fighting-types to gain yet ANOTHER advantage over other Pokemon).
Seriously, GameFreak? Seriously? I know that you're nicknamed TrollFreak for a reason, but still.
Fairy-types being strong against Dark-types doesn't really make sense science-y wise. I say this because no matter how you view/interpret them, Dark-types being weak to Fairies doesn't make sense. If you view Dark-types as just a broad category for "evil", then Fairies being naturally strong against them fails because the fairies in fairy tales were just as capable of being evil as they were of being good. If you view Dark-types as utilizing dark arts such as black magic and stuff like that, then Fairies being strong against them doesn't work because, again, Fairies were just as capable of committing evil acts and using bad magic as they were of performing benign acts and using good magic. If you view Dark-types as Combat Pragmatists (like TV Tropes does), then Fairies being strong against them doesn't make sense simply because they don't connect. Mythical creatures being strong against creatures that aren't afraid to fight dirty makes about as sense as creatures that have pyrokinetic abilities (Fire-types) being strong against dirt (Ground-types). They don't really seem to connect.
Also, as well as not making sense science-y wise, Fairies being strong against Dark-types wouldn't make sense metagame-wise. The Dark-type, as we know, is only strong against Psychic-types and Ghost-types. They are immune to Psychic-types moves and resist themselves. They're already weak to Fighting-types (which are EVERYWHERE) and Bug-types (which, with Scizor, Volcarona, and Genesect running around, are quite popular - and let's not forget the ubiquitous U-Turn). Fairy-types are going to be quite popular due to their touted advantages against the powerful Dragon-type. The purpose of the Fairy-type is to help balance the metagame. However, will they really be doing this if their attacks are also super-effective against the struggling Dark-type? I don't think so.
That's my fifty cents on the issue. Feedback? Opinions? Flames? I'm open to all except the last one.
I've heard ice is rumored to be weak to it as well. They don't need another weakness.
^Sadly, he probably won't evolve it.
^I could see that.
