I could expect that there would be 5,000,000 pre-orders for the 3DS but that doesn't mean there will be 5,000,000 pre-orders for the 3DS.
Personally, I would be surprised if Microsoft allowed more than 500,000 pre-orders to be issued for Kinect world wide being that they (probably) won't want people who pre-ordered to be waiting weeks/months to receive their hardware.
