Am on the list here in NZ from my local dealer to 'come and get it' the day it's released. From what I was told (Hi Michael, if you're reading this!) is that when Tiger was released they opened up for an hour or so at midnight that day and called people in who were on the list to buy.
So, because NZ is one of the first countries to welcome in the day, I and any other Kiwi Macheads may be some of the first to install it. We may lose at the rugby world cup (so did AUS!), but first for Leopard!
