The DS XL - known as the DS LL in Japan - is something of a monster. Want proof? Check out this official promotional video, which has been released by Nintendo to advertise the impending Japanese launch of the console.
The footage shows an almost unbearably happy Japanese family fawning over their new DS LL, and gives a good impression of just how chunky the new console is. It also shows the dimensions of the new stylus.
The new handheld comes out over there next week, so if you're planning to import then you'd better get your skates on. The Western release is expected early next year.
