Well, some thoughts on the approach used to build the new Lucario:
I've watched the stream, and his new style seems very, very cool. The whole idea of several canceling moves seems great, and might add a lot to the character.
My only concern is how he fits into the fighting-style of Super Smash Brothers. I'm not even talking about balance here. He might end up crap, on god tier, we can't judge that right now.
The real question is: Does he fit well into the Smash-Style? We never had a character with those capabilities before, and even the most weirdest smash fighters don't have anything in common with that.
This might work, but I would like to hear (read) what were the designer's thoughts when deciding this approach, and how you guys plan to make him fit well into the game.
Also, should we consider giving those capabilities to other characters as well?
