Apple will be reporting its third-quarter fiscal year 2012 earnings call later today, and many are speculating that part of that call will be the announcement of the OS X Mountain Lion release date. In fact, last year Lion's release date was announced during the earnings call, and it debuted the following day. Apple has promised that Mountain Lion would be released this month, and we've got a week left. If we had to bet, we'll see Apple's next major operating system launch tomorrow. Mountain Lion will be available on the Mac App Store for $19.99, and the Golden Master was released to developers recently.
