If Nintendo wants to launch a new SKU they have to convince retailers to stock them. And as much as people round here complain about it, I doubt the mass market is looking at the Wii U and saying, "Man, I'd buy that yesterday, if only it came with a built-in HDD."
I wish people would stop describing their dream SKUs. If Nintendo made a SKU with hotrod flames painted on the Wii U and gave it a 1 TB HDD, 8 gigs of RAM, dropped the GamePad from the bundle but included two Pro Controllers plated with solid gold, bundled with Metroid Prime HD Trilogy, sold for $250, I'd be all over it. They should do that because obviously everyone wants the same thing as me and there's no way they would be bleeding money from every orifice if they did something like that.
