actually, that's not true. It's been in release client forms and to developers writing drivers, but that's about it. to get it (minus the normal, illegal channels) you had to apply up until last monday to be one of the testers. Unless you can buy it for a machine from a manufacturer or in a retail box, I wouldn't consider it released.
