Mario Party 9 Trailer!

I wonder if Bowser Jr. will be playable or just be a character to play against in the story mode. If he was playable though it would be kinda of weird if Bowser would be taking coins and stars from his own son!

That's precisely why he wouldn't be a playable character as seen from the screens in the first place. But if he was a secret playable character, well, still, that would be crazy. But, it's still speculation at this time.
