All players are now sold. The 60GB players were considerably over subscribed, but most of those customers have been offered 30GB as an alternative.
There is a slim chance that more players could become available, for example if we get failed payments, in which case they will be offered to customers who have already attempted to order, and then thrown open. I'll post updates here - NB we're not maintaining a queue because it is unlikely that any more players will become available.
It looks like the US store still has 20GB and 30GB players.
