New Pokemon Black and White Legendaries! also spring 2011 US Release!

Well Pokemon.com has showed these new Legendary Pokemon for the upcoming version for Pokemon Black and Pokemon White; it's also announced for US release in Spring 2011. These new Legendaries are called Reshiram(left) and Zekrom(right), both are dragon types, and my predictions are they will be of a light/dark realm or world (just a prediction though). I'm thinking a light/dark realm will be probably best suited since the other Pokemon Legendaries already have dibs on other worldly elements(also incorporate with Giratina and its Distortion World...but this is all speculation...)...ill put more info as it arrives on Pokemon Black & White and then maybe give my own suggestions on the new 5th gen pokemon...
