Why does Nintendo limit WiiU stock and intentionally cause shortages, again?

Again, they did what they did as they did with the Wii.

They clearly undershipped the amount pre-order units allowed.

Next gen hasn't started yet, apparently.  What does Nintendo gain by oversupplying vs undersupplying?

Nintendo is clearly limiting the number of pre-orders. It's sold out in a day. What proof do you need?
