In BW2 there's nothing indicating that they could be the Striaton Bros.
This means that Kusaka will probably conform to the games and this will turn out to be a huge red herring.
I won't even be surprised if their designs are changed when BW gets collected into Tankobons in order to make them look more like in the Animated Trailer (and the game intro). The Pokemon that they use may get changed too.
Kusaka & Yamamoto made a mistake but they've still got time to rectify it. I think they should do it, instead of pulling it harder. I don't like such changes and I really don't miss the times when practically everyone was a villain in PokeSpe.
I don't come here as often as I used to, do I?
