Kamen Rider Decade is ending early this year. (I can't fathom it being because of a lack of popularity. It might just have been planned this way from the beginning.) Well, Japan has the answer for the Kamen Rider blues - with another Kamen Rider series beginning right after Decade ends.
The new Rider is Kamen Rider Double. (I don't know if "Kamen Rider W" is also correct) It's going to feature two people combining to become Double. That simple idea if just rife with possibilities.
So, anyway, here are some images of Kamen Rider Double.
