Smash Bros. Music Video + New japanese game for 3DS Puzzle & Dragons: Super Mario Edition

[Darwinianevolution]

Is the P&D game going to be just a reskin for western audiences, or it's going to be a different thing?
Also, every time I read now "New 3DS game" I don't know if it's a new incoming 3DS title or it's going to the New 3DS.
