Ok sorry for the short version. Now I reveal my thoughts about the new Eeveelution and my theory of it being a dream type.
First of all you need to look at this video of sylveon using a couple of attacks ingame:
>> the attacks I want to focus on are the third and especially the last one, which is obviously Swift.
And the second video, the last part of the latest trailer for the new film:
www.youtube.com/watch?feature=… (I skipped the boring part with Mewtwo and Genesect or you xD)
Notice the stars in the background while Sylveons showing off? And again everything turns darker at first just like in the third attack of the first video.
Also, Sylveon seems to have absolute control over those ribbons. Why is that? It certainly possesses some kind of magic (which could lead to a magic type, but I think that would not fit it)
In the next step everything turns dark and suddenly everything looks like a nice trip on a drug of your choice xD.
Now as everyone knows, there are several Pokemon that have this super cute look. Yes I'm looking at the pink ones, especially Clefairy, Jigglypuff, Chansey, Skitty and their evolutions(of course there are more that do fit in this category) also Cresselia.
In the last versions (Black/White) the theme was all about wish and truth. Pokemon could enter the dreamworld and make their dreams reality, letting you catch some monsters with powers they were never supposed to have. And guess what Pokémon made it possible to make their dreams come true? Pink ones again! Munna and Musharna.
Furthermore, most the cute Pokémon I listed before learn the move sing, which puts others to sleep. Jigglypuff even had its own song "Jiglypuff's lullaby". And what do we do under this condition (I know it's a rare case, staying up all night is just so awesome xD): We dream. Also the majority of the cute Pokés learns either wish or healing wish and sometimes Moonlight. All things that can be related to sleep and dreams somehow. Also Cresselia, do I need to say more?
So I guess Ninfia and other Cuteymons are going to get a new type, which hopefully will be >DREAM<
I would love to see a new type and I'm so hyped about X and Y right now.^^ I hope I explained everything well enough for you to understand.
