Morning Wilts,
I think pr00ne is referring to the confirmed orders from the partner nations:
Great Britain 232
Germany 180
Italy 121
Spain 87
Total 620
Not sure if Austria has actually signed up yet and Greece is still a possibilty. Then there is Saudi Arabia possibly and I'm not so sure that Singapore is completely out of the equation. A couple of question marks there but I think the total figure will be a lot more than 600.
