10.7 isnt available anywhere now.
10.8.1 downloading now.
....That's bad if 10.7 is no longer available. There are plenty of professional areas where users want 10.7 but not 10.8 yet. Having said that, most of the OS updates seem to be user interface features which aren't so important anyway. 10.6 is thought very highly of.
I downloaded the 10.7 Lion installer months ago and will download the 10.8 installer soon but probably not load it until 10.9 is released.
So Mountain Lion is up to 10.8.1 already.
