Keldeo's slightly taller, his hooves have changed, his hair has gown, his mane is bigger, his limbs are slightly muscular, his "eyebrows" are different, and his horn is different.

So the final Black 2 & White 2 information from CoroCoro is out and here's the important stuff:

1. Version Exclusives: Buneary and Magby for Black 2 & Skitty and Elekid for White 2. (Version exclusives, usual deal. Though I do find it interesting that it's the Fire-type going to Black 2 (which has the Electric Dragon Zekrom Kyurem forme, Black Kyurem) and the Electric-type is going to White 2 (which has the Fire Dragon Reshiram Kyurem forme, White Kyurem). Hint that everything isn't what it seems to be?)
2. The cities have been vastly changed from Black 2 & White 2. (How much one of these changes include new heating systems? )
3. PokeTransfer works between all DS games. (No reason to take it out really. Plus it gives them an explanation why their are non-Unova Pokemon suddenly appearing all over Unova *coughinvasivespeciescough*)
4. Version Exclusive Areas: White Forest and Black City return. Also there are two version exclusive caves, one based around WATER and another based around MAGMA. (... yeah, as subtle as a brick to the face. )
5. Elesa has indeed changed her outfit to the one she's wearing in the animated trailer. Her Gym is also now fashion show based. She also now uses a Flaaffy. (Well the rollercoaster gym, while amusing, really didn't make much sense for a Gym Leader who's a fashion model.)
6. To change Keldeo to its Resolution Forme, you need to have Terrakion, Virizion, and Cobalion and take all four of them to the forest in Sangi Town. It also learns the move Sacred Sword. Resolution Forme's heights is 1.4m and weighs 48.5kg. (We also got to see what Resolution Forme looks like and... it's just Keldeo with a bigger horn, shorter eyebrows, and three colored hair pieces each representing the main color of Terrakion, Virizion, and Cobalion. Otherwise it looks the same as it did before!)
7. You can get a Porygon with the Dream Radar (*insert insensitive 3D giving seizure joke here*)
8. The item to change Tornadus, Thundurus & Landorus into their Sacred Beast Formes is called Reflecting Mirror. They also gain a new Ability: Tornadus gets Regenerator, Thundurus gets Volt Absorb, and Landorus gets Intimidate. ("Reflecting Mirror", hmm, well that goes above 12 characters so expect that to get a name change.)

Well, nothing now left to do but wait till Black 2 & White 2 are officially released... and I try to avoid spoilers though will probably ultimately fail...

Basically, our little pony has grown up a bit. ...now i sorta want a super special pokemon episode where they do crossover with MLP for no reason.

ELEKID ON WHITE 2. AW HELL YES. Getting him on my team, if i can't get the evolution item at an appropriate time during the storyline, i'll just get one in white before the games come out. Give him Earthquake right away while i'm at it.

Line-up:

***SPOILER***

hopefully the trading items won't be too far behind the area where you may catch the certain pokemon. I want a magmortar on my team dang it!!
