AppleInsider is reporting that Mac OS X 10.5 (Leopard) will be released on October 26th, according to sources at Apple.

Excerpt from AppleInsider:

While sources have requested that we not go into detail regarding the specific measures being put into place, they say the announcements are likely to arrive any time between the 22nd and 27th of the month.

Obviously, such a timeframe would coincide with Apple’s self-imposed release schedule for Mac OS X Leopard, which the company – after having delayed the software once – has promised for “October.”

Despite the operating system not having yet achieved golden master status, recent builds have seen very short known issues lists.

According to MacNN:

Apple has traditionally used the final Friday of the month to roll out major Mac OS X upgrades. In Late-August, a copy of Apple’s Mac OS X 10.5 Leopard introduction video surfaced on YouTube, displaying the company’s traditional “Welcome” message in numerous languages set atop a deep-space theme. A simple techno beat accompanies a warm introduction for new Leopard users when installation completes.

Apple said earlier this year that Mac OS X Leopard will be delayed until October. This is to allow the company to devote more of its resources towards the development of the iPhone.
