Am I mistaken with my terms, or technically is there no such thing as a "gold master" for OS X Lion? Given that it is supposed to be purely a digital release, a gold master (physical golden disc used as a master template for CD/DVD production factories) cannot exist?
The term still may apply though, in that it is the "final and locked in" version of the code that will be released to the public. However, again considering the digital only nature of Lion, the time frame from "GM release" to "public release" can be exceedingly short, since there is no need to actually ship a golden master to a factory and have physical media made. Really wouldn't all they would need to do would be to upload it to the mac app store server and that's it?
