Do we know how many HL2-packages there have been sold?

[Frutkola]

It could be kinda exsiting to know how many copies of HL2 there already have been sold due the bronze, silver and gold packages. :O

We don't know and it would be nice to see. Valve might indeed publish how many and in what time they have sold. Just to show off.

I am also interested in the sales numbers. I bet they are staggering.
