The Wind Waker bundle seems to be moving slowly in my area, the NSMBU bundle is doing better, but retailers didn't order as much of the NSMBU bundle because they loaded up on the Zelda one.
The Zelda bundle kinda is a ripoff by comparison, NSMBU + NSLU is basically two games on content that are newer, Wind Waker HD is one game and an old game at that, just re-upped in HD.
I think there are going to be a lot of $250 Black Friday deals for Wii U for both bundles which sold help move consoles.
