That was only Manaphy, Darkrai and Shaymin. Arceus was able to rename in BW from the DW event.

Diancie is now live for PAL regions, including Europe, Australia and New Zealand. I am unsure if or when the US region goes live, but it should be very soon!

Also, it is worth noting that ORAS has achieved a feat no other Pokemon game has done, not even RBY, and that is continue to keep me playing long after I have finished the Elite Four. I am still not bored of this game, and that's incredible in this day and age and with my increasingly short attention span.

Diancie is indeed live here in the US.

I thought it was supposed to have a Rare Candy on it?

Same. In fact, I'm up to over 7,300 flags in my Super-Secret Base and still going up.

Got Diancie!

What are Eevee and its evolutions? Cats or dogs?

Depends.

Eevee is rather fox-like.
Vaporeon: I'd say is more cat-like
Jolteon: A bit doggy, but more cat-like.
Flareon: Rather hard to pin down, but I say cat
Espeon: Definitely cat, given it's basically a Nekomata.
Umbreon: Also hard to pin down. He's more fox-like than anything.
Leafeon: More cat-like
Glaceon: Also rather cat-like
Sylveon: A weird mix of everything. It has a more cat-like face, but it's ears are more like a cat, but it's tail is more dog-like.

They're more vulpine and catlike. Only very few dog like traits among them.

I see. I also didn't see many canine features among them.

I'm wondering if Umbreon passes for a black cat?
