A few tasty tidbits from the latest NP issue's preview of NSMBW:
-Each Koopaling is the world's boss, having to be fought twice: once in a midworld fortress and once at the end castle.
-For the Koopaling rematches, Kamek returns to assist them with magic (ala Yoshi's Island).
-Bonus card games make their return from SMB3.
-The full item list is revealed. Sadly, Mega Mushrooms and Blue Shells have been removed.
-For those who are worried about Bowser Jr. replacing Bowser, don't worry; the Big B will make his appearance at the game's climax (as per usual).
-The game can be played in wide-screen, which automatically zooms in and out depending on the number of players.
-NSMBW will apparently be one of the hardest games in the entire Mario series.
