Hummm - seems loads of people will be breaking various license agreements to get it installed without buying it.
Borrowing it from work, installing it under work schemes (you're all going to have to tell me about this magical work license agreements whereby people are allowed to install the OS on home machines - cannot say I've seen them and I'm paid to know about them).
The MSDN versions only get 10 activations - so I guess once a place of work has done its illegal distribution of the MSDN download 10 times and all those people have activated that will put that key out of action for a while.
Maybe if the OP had wanted a better idea of who will actually be buying what you should have asked for just people who were actually going to go out and buy it and get it legally.
