that link isn't working and I'm too lazy to type it in manualy (or copy paste

), but since I read about this yesterday somewhere else, I'll tell you what I remember.
MS told european retailers that they will allow thier store 20 consoles on launch day (6 core & 14 premium) on two conditions.
1. They must sell every single console on launch day.
&
2. They must sell
atleast 2 games with each console sold.
if both of those conditions were met then they were eligible to recieve more consoles ASAP.

Gizmodo reports that in Norway, the launch marketing campaign aims to build hype around the console by trumpeting its "SOLD OUT!" status to would-be buyers. In addition to limiting the per-store stock of consoles and having the retailers prepare to prominently note the unit's "sold out" status, Microsoft has allegedly asked Norwegian retailers to sign an agreement that they'll sell out of the consoles on the launch date.
Here in the states, Kotaku leaks the details of Target's launch preparations. From Kotaku's Target mole:
The average store can expect to have between 25 and 50 consoles the first day, but it mentions elsewhere that this number can be as low as 10. This is all determined by average store volume. I checked the computer and the consoles, games and peripherals are already in the system, so if you have a generous Target employee they can check to see exactly the amount of consoles they have in when they get the shipment.
On Nov. 22:
Every store will print up tickets representing the number of 360's and core systems they have in stock. They are also supposed to print a large sign informing customers that the store has sold out and keep it on hand.
I saw a slightly different quote yesterday, if I find it I'll edit this post and put it here
