You do realize that the past two weeks is when the special edition went up for sale right? Yeah, and it has been available to pre-order from Gamestop. There has been no limit to the pre-orders for it there. So it makes perfect sense why it has gotten 40k pre-orders in the last two weeks.
Also keep in mind it's one of the main games that a lot of people have been waiting to get a Wii U for, and it's pretty much the only big hitter system seller this holiday. I imagine in a month we will see some heavy advertising for it as well.
