Yes. As best as can be determined at this time. The Windows 8 GA (General Availability) will be on or about that date. Always subject to a push due to some unforeseeable circumstances which might result in some delay, although I suspect that with the Holiday Shopping Season fast approaching at that time they'll likely hit that date.
Going to be a busy time in the Halls O' Microsoft. Windows 8 and Windows 8 Pro, Windows 8 RT / Surface, hoping to see Windows 8 Pro / Surface (then or shortly there after), Windows Phone 8, all expected to make their debut about the same time.
